Setup

class "img-lightbox-link" is required, and can be any name you choose.

data-src is another method to get the source URL when you do not want the link to lead to some real URL.

href is required, and contains URL of your image.

For those who don't use 3rd-party scripts that interfere with links behaviour and don't force window.location they have no need in either data-touch="true" or {touch: true}.

When you have scripts that interfere, then to keep lightbox working, use {touch: true} or data-touch="true".

data-src or href doesn't matter, but you shouldn't enable touch override if you have a full screen image in a lighbox link and have no other space to scroll down.

<a href="https://farm1.staticflickr.com/955/27854475488_4f2b7f52e4_k.jpg"
class="img-lightbox-link"
data-src="https://farm1.staticflickr.com/955/27854475488_4f2b7f52e4_k.jpg"
aria-hidden="true"
rel="lightbox"><img src="https://farm1.staticflickr.com/955/27854475488_5f82a379ca_z.jpg" alt="Image Lightbox" /></a>

Initialize

imgLightbox("img-lightbox-link");

Tips

SPA / PWA developers don't need to bother: built-in class is added to a link.

That way you avoid multiple assignments to a single element.

Examples of event handling

(function(root) {
   "use strict";
   if (root.imgLightbox) {
   	imgLightbox("img-lightbox-link", {
   		onCreated: function() {
   			/* show your preloader */
   		},
   		onLoaded: function() {
   			/* hide your preloader */
   		},
   		onError: function() {
   			/* hide your preloader */
   		},
   		onClosed: function() {
   			/* hide your preloader */
   		},
   		rate: 500 /* default: 500 */,
   		touch: false /* default: false - use with care for responsive images in links on vertical mobile screens */
   	});
   }
})("undefined" !== typeof window ? window : this);
