blueimp Gallery is a touch-enabled, responsive and customizable image and video gallery, carousel and lightbox, optimized for both mobile and desktop web browsers.
It features swipe, mouse and keyboard navigation, transition effects, slideshow functionality, fullscreen support and on-demand content loading and can be extended to display additional content types.
Install the blueimp-gallery package with NPM:
npm install blueimp-galleryCopy the css, img and js directories to your website.
Include the Gallery stylesheet in the head section of your webpage:
<link rel="stylesheet" href="css/blueimp-gallery.min.css" />Add the following HTML snippet with the Gallery widget to the body of your webpage:
<!-- The Gallery as lightbox dialog, should be a document body child element -->
<div
id="blueimp-gallery"
class="blueimp-gallery"
aria-label="image gallery"
aria-modal="true"
role="dialog"
>
<div class="slides" aria-live="polite"></div>
<h3 class="title"></h3>
<a
class="prev"
aria-controls="blueimp-gallery"
aria-label="previous slide"
aria-keyshortcuts="ArrowLeft"
></a>
<a
class="next"
aria-controls="blueimp-gallery"
aria-label="next slide"
aria-keyshortcuts="ArrowRight"
></a>
<a
class="close"
aria-controls="blueimp-gallery"
aria-label="close"
aria-keyshortcuts="Escape"
></a>
<a
class="play-pause"
aria-controls="blueimp-gallery"
aria-label="play slideshow"
aria-keyshortcuts="Space"
aria-pressed="false"
role="button"
></a>
<ol class="indicator"></ol>
</div>Please note that each aria-controls attribute should have the same value as
the id attribute of the Gallery widget.
Include the Gallery script at the bottom of the body of your webpage:
<script src="js/blueimp-gallery.min.js"></script>Create a list of links to image files, optionally with enclosed thumbnails and add them to the body of your webpage, before including the Gallery script:
<div id="links">
<a href="images/banana.jpg" title="Banana">
<img src="images/thumbnails/banana.jpg" alt="Banana" />
</a>
<a href="images/apple.jpg" title="Apple">
<img src="images/thumbnails/apple.jpg" alt="Apple" />
</a>
<a href="images/orange.jpg" title="Orange">
<img src="images/thumbnails/orange.jpg" alt="Orange" />
</a>
</div>Add the following JavaScript code after including the Gallery script, to display the images in the Gallery lightbox on click of one of those links:
<script>
document.getElementById('links').onclick = function (event) {
event = event || window.event
var target = event.target || event.srcElement
var link = target.src ? target.parentNode : target
var options = { index: link, event: event }
var links = this.getElementsByTagName('a')
blueimp.Gallery(links, options)
}
</script>To initialize the Gallery with visible controls (previous slide, next slide,
etc.), add the CSS class blueimp-gallery-controls to the Gallery widget:
<div
id="blueimp-gallery"
class="blueimp-gallery blueimp-gallery-controls"
aria-label="image gallery"
aria-modal="true"
role="dialog"
>
<!-- ... -->
</div>Please also note that by default, a click on an image slide or any Gallery
widget element with the toggle class will toggle the display of the Gallery
controls.
To stretch smaller images to the dimensions of the Gallery container while
keeping their aspect ratio, add the CSS class blueimp-gallery-contain to the
Gallery widget:
<div
id="blueimp-gallery"
class="blueimp-gallery blueimp-gallery-contain"
aria-label="image gallery"
aria-modal="true"
role="dialog"
>
<!-- ... -->
</div>To display the images in an inline carousel instead of a lightbox, follow the
lightbox setup and add the CSS class
blueimp-gallery-carousel to the Gallery widget and remove the child element
with the close class, or add a new Gallery widget with a different id to
your webpage:
<!-- The Gallery as inline carousel, can be positioned anywhere on the page -->
<div
id="blueimp-gallery-carousel"
class="blueimp-gallery blueimp-gallery-carousel"
aria-label="image carousel"
>
<div class="slides" aria-live="off"></div>
<h3 class="title"></h3>
<a
class="prev"
aria-controls="blueimp-gallery-carousel"
aria-label="previous slide"
></a>
<a
class="next"
aria-controls="blueimp-gallery-carousel"
aria-label="next slide"
></a>
<a
class="play-pause"
aria-controls="blueimp-gallery-carousel"
aria-label="play slideshow"
aria-pressed="true"
role="button"
></a>
<ol class="indicator"></ol>
</div>Add the following JavaScript code after including the Gallery script to initialize the carousel:
<script>
blueimp.Gallery(document.getElementById('links').getElementsByTagName('a'), {
container: '#blueimp-gallery-carousel',
carousel: true
})
</script>The Gallery supports the concept of
responsive images
with the srcset, sizes and sources object properties, e.g. using the
API:
var gallery = blueimp.Gallery([
{
title: 'Banana',
href: 'https://example.org/images/banana-1024w.jpg',
srcset:
'https://example.org/images/banana-800w.jpg 800w,' +
'https://example.org/images/banana-1024w.jpg 1024w,' +
'https://example.org/images/banana-1600w.jpg 1600w',
sizes: '(min-width: 990px) 990px, 100vw',
thumbnail: 'https://example.org/images/banana-75.jpg'
},
{
title: 'Apple',
href: 'https://example.org/images/apple.png',
sources: [
{
type: 'image/svg+xml',
srcset: 'https://example.org/images/apple.svg'
},
{
type: 'image/webp',
srcset: 'https://example.org/images/apple.webp'
}
]
}
])With link elements, those same properties can be defined via data-srcset,
data-sizes and data-sources attributes:
<div id="links">
<a
title="Banana"
href="images/banana-1024w.jpg"
data-srcset="images/banana-800w.jpg 800w,
images/banana-1024w.jpg 1024w,
images/banana-1600w.jpg 1600w"
data-sizes="(min-width: 990px) 990px, 100vw"
>
<img src="images/banana-75.jpg" alt="Banana" />
</a>
<a
title="Apple"
href="images/apple.png"
data-sources='[
{
"type": "image/svg+xml",
"srcset": "images/apple.svg"
},
{
"type": "image/webp",
"srcset": "images/apple.webp"
}
]'
>Apple</a
>
</div>Please note that data-sources must be a valid
JSON string listing
the sources array.
The Gallery can be controlled with the following keyboard shortcuts:
Enter: Toggle controls visibility.Escape: Close the Gallery lightbox.Space: Toggle the slideshow (play/pause).ArrowLeft: Move to the previous slide.ArrowRight: Move to the next slide.
Please note that setting the carousel option to true disables the keyboard
shortcuts by default.

// Callback function executed when the Gallery is initialized.
},
onopened: function () {
// Callback function executed when the Gallery has been initialized

},
onclose: function () {
// Callback function executed when the Gallery is about to be closed.
},
onclosed: function () {
// Callback function executed when the Gallery has been closed
// and the closing transition has been completed.
}
})If the carousel option is true, the following options are set to different
default values:
var carouselOptions = {
hidePageScrollbars: false,
toggleControlsOnEnter: false,
toggleSlideshowOnSpace: false,
enableKeyboardNavigation: false,
closeOnEscape: false,
closeOnSlideClick: false,
closeOnSwipeUpOrDown: false,
closeOnHashChange: false,
disableScroll: false,
startSlideshow: true
}The options object passed to the Gallery function extends the default options
and also those options set via carousel mode.
The following are the additional default options set for the slide position indicator:
var indicatorOptions = {
// The tag name, Id, element or querySelector of the indicator container:
indicatorContainer: 'ol',
// The class for the active indicator:
activeIndicatorClass: 'active',
// The list object property (or data attribute) with the thumbnail URL,
// used as alternative to a thumbnail child element:
thumbnailProperty: 'thumbnail',
// Defines if the gallery indicators should display a thumbnail:
thumbnailIndicators: true
}The following are the additional default options set for the fullscreen mode:
var fullscreenOptions = {
// Defines if the gallery should open in fullscreen mode:
fullscreen: false
}The following are the additional default options set for the video factory:
var videoFactoryOptions = {
// The class for video content elements:
videoContentClass: 'video-content',
// The class for video when it is loading:
videoLoadingClass: 'video-loading',
// The class for video when it is playing:
videoPlayingClass: 'video-playing',
// The class for video content displayed in an iframe:
videoIframeClass: 'video-iframe',
// The class for the video cover element:
videoCoverClass: 'video-cover',
// The class for the video play control:
videoPlayClass: 'video-play',
// Play videos inline by default:
videoPlaysInline: true,
// The list object property (or data attribute) for video preload:
videoPreloadProperty: 'preload',
// The list object property (or data attribute) for the video poster URL:
videoPosterProperty: 'poster'
}Options for YouTube videos:
var youTubeOptions = {
// The list object property (or data attribute) with the YouTube video id:
youTubeVideoIdProperty: 'youtube',
// Optional object with parameters passed to the YouTube video player:
// https://developers.google.com/youtube/player_parameters
youTubePlayerVars: undefined,
// Require a click on the native YouTube player for the initial playback:
youTubeClickToPlay: true
}Options for Vimeo videos:
var vimeoOptions = {
// The list object property (or data attribute) with the Vimeo video id:
vimeoVideoIdProperty: 'vimeo',
// The URL for the Vimeo video player, can be extended with custom parameters:
// https://developer.vimeo.com/player/embedding
vimeoPlayerUrl:
'https://player.vimeo.com/video/VIDEO_ID?api=1&player_id=PLAYER_ID',
// The prefix for the Vimeo video player ID:
vimeoPlayerIdPrefix: 'vimeo-player-',
// Require a click on the native Vimeo player for the initial playback:
vimeoClickToPlay: true
}The widget container, slidesContainer, titleElement and
indicatorContainer options can be set as
CSS selector
or HTMLElement node, so the following are equivalent:
var options = {
container: '#blueimp-gallery'
}var options = {
container: document.getElementById('blueimp-gallery')
}CSS selectors are passed as argument to querySelectorAll, which is supported by IE8+ and all modern web browsers and queried with getElementById or getElementsByTagName in older browsers.
If the helper script is replaced with jQuery, the container and element options can be any valid jQuery selector.
The options ending with "Property" define how the properties of each link
element are accessed.
For example, the urlProperty is by default set to href. This allows to
define link elements with href or data-href attributes:
<div id="links">
<a href="images/banana.jpg">Banana</a>
<a data-href="images/apple.jpg">Apple</a>
</div>If the links are provided as JavaScript array, it is also possible to define nested property names, by using the native JavaScript accessor syntax for the property string:
blueimp.Gallery(
[
{
data: { urls: ['https://example.org/images/banana.jpg'] }
},
{
data: { urls: ['https://example.org/images/apple.jpg'] }
}
],
{
urlProperty: 'data.urls[0]'
}
)The blueimp Gallery can be initialized by simply calling it as a function with an array of links as first argument and an optional options object as second argument:
var gallery = blueimp.Gallery(links, options)The links array can be a list of URL strings or a list of objects with URL properties:
var gallery = blueimp.Gallery([
'https://example.org/images/banana.jpg',
'https://example.org/images/apple.jpg',
'https://example.org/images/orange.jpg'
])var gallery = blueimp.Gallery([
{
title: 'Banana',
type: 'image/jpeg',
href: 'https://example.org/images/banana.jpg',
thumbnail: 'https://example.org/thumbnails/banana.jpg'
},
{
title: 'Apple',
type: 'image/jpeg',
href: 'https://example.org/images/apple.jpg',
thumbnail: 'https://example.org/thumbnails/apple.jpg'
}
])The URL property name defined by each list object can be configured via the
urlProperty option. By default, it is set to href, which allows to pass a
list of HTML link elements as first argument.
For images, the thumbnail property defines the URL of the image thumbnail,
which is used for the indicator navigation displayed at the bottom of the
Gallery, if the controls are visible.
The object returned by executing the Gallery function (the gallery variable in
the example code above) is a new instance of the Gallery and allows to access
the public API methods provided by the Gallery.
The Gallery initialization function returns false if the given list was empty,
the Gallery widget is missing, or the browser doesn't pass the functionality
test.
The Gallery object returned by executing the Gallery function provides the following public API methods:
// Return the current slide index position:
var pos = gallery.getIndex()
// Return the total number of slides:
var count = gallery.getNumber()
// Move to the previous slide:
gallery.prev()
// Move to the next slide:
gallery.next()
// Move to a slide index with the (optional) duration in milliseconds:
gallery.slide(index, duration)
// Start an automatic slideshow with the (optional) interval in milliseconds:
gallery.play(interval)
// Stop the automatic slideshow:
gallery.pause()
// Add additional slides after Gallery initialization:
gallery.add(list)
// Close and deinitialize the Gallery:
gallery.close()The Gallery can be initialized with a list of videos instead of images, or a combination of both:
blueimp.Gallery([
{
title: 'Fruits',
type: 'video/mp4',
href: 'https://example.org/videos/fruits.mp4',
poster: 'https://example.org/images/fruits.jpg'
},
{
title: 'Banana',
type: 'image/jpeg',
href: 'https://example.org/images/banana.jpg',
thumbnail: 'https://example.org/thumbnails/banana.jpg'
}
])The Gallery uses the type property to determine the content type of the object
to display.
If the type property is empty or doesn't exist, the default type image is
assumed.
Objects with a video type will be displayed in a
HTML5 video element
if the browser supports the video content type.
For videos, the poster property defines the URL of the poster image to
display, before the video is started.
To start video playback, you can either click on the video play icon or on the
video slide itself.
Starting the video playback enables the native HTML5 video
controls.
To toggle the Gallery controls (previous slide, next slide, etc.) instead of
starting video playback on click of a video slide, add the toggle class to the
video cover element using the videoCoverClass Gallery option:
blueimp.Gallery(
[
{
title: 'Fruits',
type: 'video/mp4',
href: 'https://example.org/videos/fruits.mp4',
poster: 'https://example.org/images/fruits.jpg'
}
],
{
videoCoverClass: 'video-cover toggle'
}
)You can set the preload property of a Gallery video object to a valid value
defined by the HTML5 video
preload
attribute:
none: Indicates that the video should not be preloaded.metadata: Indicates that only video metadata (e.g. length) is fetched.auto: Indicates that the whole video file can be preloaded.
blueimp.Gallery([
{
title: 'Fruits',
type: 'video/mp4',
href: 'https://example.org/videos/fruits.mp4',
preload: 'auto'
}
])By default, preload is set to none to save on network bandwidth consumption.
By default, videos are displayed with the HTML5 video
playsinline
attribute set, which indicates that the video is to be played inline.
To disable this behavior, you can set the Gallery option videoPlaysInline to
false:
blueimp.Gallery(
[
{
title: 'Fruits',
type: 'video/mp4',
href: 'https://example.org/videos/fruits.mp4',
poster: 'https://example.org/images/fruits.jpg'
}
],
{
videoPlaysInline: false
}
)Please note that this attribute only has an effect on some mobile browsers, e.g.
Safari on iOS 10 and later.
However, all browsers provide video controls to switch between fullscreen and
inline mode on user request.
To provide multiple video formats, the sources property of a list object can
be set to an array of objects with type and src properties for each video
source. The first video format in the list that the browser can play will be
displayed:
blueimp.Gallery([
{
title: 'Fruits',
type: 'video',
sources: [
{
type: 'video/mp4',
src: 'https://example.org/videos/fruits.mp4'
},
{
type: 'video/ogg',
src: 'https://example.org/videos/fruits.ogv'
}
],
poster: 'https://example.org/images/fruits.jpg'
}
])It is also possible to define the video sources as data-sources attribute as a
JSON string listing
the sources array:
<div id="links">
<a
title="Fruits"
type="video/mp4"
href="https://example.org/videos/fruits.mp4"
data-sources='[
{
"type": "video/mp4",
"src": "videos/fruits.mp4"
},
{
"type": "video/ogg",
"src": "videos/fruits.ogv"
}
]'
data-poster="https://example.org/images/fruits.jpg"
>Fruits</a
>
</div>The Gallery can display YouTube videos for Gallery
items with a type of text/html and a youtube property (configurable via
YouTube options) with the YouTube video-ID:
blueimp.Gallery([
{
title: 'A YouYube video',
type: 'text/html',
href: 'https://www.youtube.com/watch?v=VIDEO_ID',
youtube: 'VIDEO_ID',
poster: 'https://img.youtube.com/vi/VIDEO_ID/maxresdefault.jpg'
}
])If the href and poster properties are undefined, they are set automatically
based on the video ID.
Please note that the Gallery YouTube integration requires a browser with postMessage support, which excludes IE7.
The Gallery can display Vimeo videos for Gallery items
with a type of text/html and a vimeo property (configurable via
Vimeo options) with the Vimeo video-ID:
blueimp.Gallery([
{
title: 'A Vimeo video',
type: 'text/html',
href: 'https://vimeo.com/VIDEO_ID',
vimeo: 'VIDEO_ID',
poster: 'https://secure-b.vimeocdn.com/ts/POSTER_ID.jpg'
}
])If the href property is undefined, it is set automatically based on the video
ID.
Please note that the Gallery Vimeo integration requires a browser with postMessage support, which excludes IE7.
It is possible to add additional elements to the Gallery widget, e.g. a description label.
First, add the desired HTML element to the Gallery widget:
<div
id="blueimp-gallery"
class="blueimp-gallery"
aria-label="image gallery"
aria-modal="true"
role="dialog"
>
<div class="slides" aria-live="polite"></div>
<h3 class="title"></h3>
<!-- The placeholder for the description label: -->
<p class="description"></p>
<a
class="prev"
aria-controls="blueimp-gallery"
aria-label="previous slide"
aria-keyshortcuts="ArrowLeft"
></a>
<a
class="next"
aria-controls="blueimp-gallery"
aria-label="next slide"
aria-keyshortcuts="ArrowRight"
></a>
<a
class="close"
aria-controls="blueimp-gallery"
aria-label="close"
aria-keyshortcuts="Escape"
></a>
<a
class="play-pause"
aria-controls="blueimp-gallery"
aria-label="play slideshow"
aria-keyshortcuts="Space"
aria-pressed="false"
role="button"
></a>
<ol class="indicator"></ol>
</div>Next, add the desired element styles to your CSS file:
.blueimp-gallery > .description {
position: absolute;
top: 30px;
left: 15px;
color: #fff;
display: none;
}
.blueimp-gallery-controls > .description {
display: block;
}Then, add the additional element information to each of your links:
<div id="links">
<a
href="images/banana.jpg"
title="Banana"
data-description="This is a banana."
>Banana</a
>
<a href="images/apple.jpg" title="Apple" data-description="This is an apple."
>Apple</a
>
</div>Finally, initialize the Gallery with an onslide callback option, to set the
element content based on the information from the current link:
blueimp.Gallery(document.getElementById('links'), {
onslide: function (index, slide) {
var text = this.list[index].getAttribute('data-description'),
node = this.container.find('.description')
node.empty()
if (text) {
node[0].appendChild(document.createTextNode(text))
}
}
})By extending the Gallery prototype with new factory methods, additional content
types can be displayed. By default, blueimp Gallery provides the imageFactory
and videoFactory methods for image and video content types respectively.
The Gallery uses the type property of each content object to determine which
factory method to use. The type defines the
Internet media type of the
content object and is composed of two or more parts: A type, a subtype, and zero
or more optional parameters, e.g. text/html; charset=UTF-8 for an HTML
document with UTF-8 encoding.
The main type (the string in front of the slash, text in the example above) is
concatenated with the string Factory to create the factory method name, e.g.
textFactory.
Please note that the textFactory script has to be included after the core Gallery script, but before including the YouTube and Vimeo integration plugins, which extend the textFactory implementation to handle YouTube and Vimeo video links.
Please also note that although blueimp Gallery doesn't require jQuery, the following example uses it for convenience.
Extend the Gallery prototype with the textFactory method:
blueimp.Gallery.prototype.textFactory = function (obj, callback) {
var $element = $('<div>').addClass('text-content').attr('title', obj.title)
$.get(obj.href)
.done(function (result) {
$element.html(result)
callback({
type: 'load',
target: $element[0]
})
})
.fail(function () {
callback({
type: 'error',
target: $element[0]
})
})
return $element[0]
}Next, add the text-content class to the Gallery CSS:
.blueimp-gallery > .slides > .slide > .text-content {
overflow: auto;
margin: 60px auto;
padding: 0 60px;
max-width: 920px;
text-align: left;
}With the previous changes in place, the Gallery can now handle HTML content types:
blueimp.Gallery([
{
title: 'Noodle soup',
type: 'text/html',
href: 'https://example.org/text/noodle-soup.html'
},
{
title: 'Tomato salad',
type: 'text/html',
href: 'https://example.org/text/tomato-salad.html'
}
])The blueimp Gallery jQuery plugin registers a global click handler to open links
with data-gallery attribute in the Gallery lightbox.
To use it, follow the lightbox setup guide, but replace the minified Gallery script with the jQuery plugin version and include it after including jQuery:
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"
integrity="sha384-nvAa0+6Qg9clwYCGGPpDQLVpLNn0fRaROjHqs13t4Ggj3Ez50XnGQqc/r8MhnRDZ"
crossorigin="anonymous"
></script>
<script src="js/jquery.blueimp-gallery.min.js"></script>Next, add the attribute data-gallery to your Gallery links:
<div id="links">
<a href="images/banana.jpg" title="Banana" data-gallery>
<img src="images/thumbnails/banana.jpg" alt="Banana" />
</a>
<a href="images/apple.jpg" title="Apple" data-gallery>
<img src="images/thumbnails/apple.jpg" alt="Apple" />
</a>
<a href="images/orange.jpg" title="Orange" data-gallery>
<img src="images/thumbnails/orange.jpg" alt="Orange" />
</a>
</div>The onclick handler from the lightbox setup guide is not
required and can be removed.
Options for the Gallery lightbox opened via the jQuery plugin can be defined as HTML5 data-attributes on the Gallery widget container.
The jQuery plugin also introduces the additional filter option, which is
applied to the Gallery links via
jQuery's filter method and allows to remove
duplicates from the list:
<div
id="blueimp-gallery"
class="blueimp-gallery"
aria-label="image gallery"
aria-modal="true"
role="dialog"
data-start-slideshow="true"
data-filter=":even"
>
<div class="slides" aria-live="off"></div>
<h3 class="title"></h3>
<a
class="prev"
aria-controls="blueimp-gallery"
aria-label="previous slide"
aria-keyshortcuts="ArrowLeft"
></a>
<a
class="next"
aria-controls="blueimp-gallery"
aria-label="next slide"
aria-keyshortcuts="ArrowRight"
></a>
<a
class="close"
aria-controls="blueimp-gallery"
aria-label="close"
aria-keyshortcuts="Escape"
></a>
<a
class="play-pause"
aria-controls="blueimp-gallery"
aria-label="play slideshow"
aria-keyshortcuts="Space"
aria-pressed="true"
role="button"
></a>
<ol class="indicator"></ol>
</div>This will initialize the Gallery with the option startSlideshow set to
true.
It will also filter the Gallery links so that only links with an even index
number will be included.
If the data-gallery attribute value is a valid id string (e.g.
"#blueimp-gallery"), it is used as container option.
Setting data-gallery to a non-empty string also allows to group links into
different sets of Gallery images:
<div id="fruits">
<a
href="images/banana.jpg"
title="Banana"
data-gallery="#blueimp-gallery-fruits"
>
<img src="images/thumbnails/banana.jpg" alt="Banana" />
</a>
<a
href="images/apple.jpg"
title="Apple"
data-gallery="#blueimp-gallery-fruits"
>
<img src="images/thumbnails/apple.jpg" alt="Apple" />
</a>
</div>
<div id="vegetables">
<a
href="images/tomato.jpg"
title="Tomato"
data-gallery="#blueimp-gallery-vegetables"
>
<img src="images/thumbnails/tomato.jpg" alt="Tomato" />
</a>
<a
href="images/onion.jpg"
title="Onion"
data-gallery="#blueimp-gallery-vegetables"
>
<img src="images/thumbnails/onion.jpg" alt="Onion" />
</a>
</div>This will open the links with the data-gallery attribute
#blueimp-gallery-fruits in the Gallery widget with the id
blueimp-gallery-fruits, and the links with the data-gallery attribute
#blueimp-gallery-vegetables in the Gallery widget with the id
blueimp-gallery-vegetables.
The gallery object is stored via jQuery data storage on the Gallery widget when the Gallery is opened and can be retrieved the following way:
var gallery = $('#blueimp-gallery').data('gallery')This gallery object provides all methods outlined in the API methods section.
The jQuery plugin triggers Gallery events on the widget container, with event names equivalent to the gallery event callbacks:
$('#blueimp-gallery')
.on('open', function (event) {
// Gallery open event handler
})
.on('opened', function (event) {
// Gallery opened event handler
})
.on('slide', function (event, index, slide) {
// Gallery slide event handler
})
.on('slideend', function (event, index, slide) {
// Gallery slideend event handler
})
.on('slidecomplete', function (event, index, slide) {
// Gallery slidecomplete event handler
})
.on('close', function (event) {
// Gallery close event handler
})
.on('closed', function (event) {
// Gallery closed event handler
})blueimp Gallery doesn't require any other libraries and can be used standalone without any dependencies.
You can also use the individual source files instead of the standalone minified version:
<link rel="stylesheet" href="css/blueimp-gallery.css" />
<link rel="stylesheet" href="css/blueimp-gallery-indicator.css" />
<link rel="stylesheet" href="css/blueimp-gallery-video.css" />
