Google Chrome extension for zooming images on mouse hover

Hover Zoom+

Google Chrome • Mozilla Firefox • Microsoft Edge

Zoom images/videos on all your favorite websites (Facebook, Amazon, etc). Hover your mouse over any image on the supported websites and the extension will automatically enlarge the image to its full size, making sure that it still fits into the browser window.

This is an open-source version of the original HoverZoom extension, which is now overrun by malware and deleted from the store. In this version all spyware has been removed, many bugs were fixed and new features were added. It doesn't collect any statistics whatsoever. The only permission it needs is to access data on all websites (to extract full images), and optional permissions to access browser history, download/save images, or get tab URLs for per-site configuration.

Sometimes sites change design, and when it happens, the extension needs to be updated. Please report any issues with zooming not working by filing an issue on https://github.com/extesy/hoverzoom/issues page.

This extension will never be sold out, and it will never compromise users' privacy.
As a proof, please see the list of all takeover offers I have received over the last few years.

Please help with localizing this extension to the language you are familiar with!

hoverzoom's Issues

Album support is broken

Chrome Version 39.0.2171.99 m
Windows 10 Technical Preview Build 9879

Issue: Going with the Action Keys Left or Right in a imgur.com hosted album, on Reddit, scrolls two photos instead of one.

Example: Album containing 10 photos. Pressing right key on image number 1 takes the user to image number 3. Pressing right key again takes the user to image number 5 and so on.

To reproduce: Install Hover Zoom+, go to Action Keys, select Left/Right as Previous/Next image (even if they are already selected). Press Save. Go on reddit.com. Find an album. Press right. You should now be on image 2, but instead Hover Zoom+ goes straight to image number 3.

Shortcut "T" doesn't work as expected

Hey,

Just switched from Hover Zoom to Hover Zoom+ and I've tried it a bit using my usual shortcuts. Unfortunately, the "T" shortcut doesn't work as expected:

Expected: Opens a new tab with a correct image url (http://i.imgur.com/dskljfsd.png).

Happened: Opens a new tab with an incorrect image url (file://i.imgur.com/OICCwRD.jpg).

Thanks a lot!

Add the '+' in Hover Zoom+

As a suggestion, you could update the repo name to match the name of your extension.
Could prevent the confusion with the original extension repo.

ebay Kleinanzeigen please

Please make your hoover zoom work on www.ebay-kleinanzeigen.de

Blink and load twice

Blink and load image twice on deviantart.com. Sometimes jump to next image.

Add an option to change volume in video previews

Mute or 100% is bad, it should be configurable. Reference: https://stackoverflow.com/questions/7582385/is-there-a-way-to-set-the-default-html5-video-volume

Feature request: Dark overlay without ambient light

Should be pretty easy to implement, just add an option to enable dark overlay background, but no ambient glow from the picture. Sometimes the ambient glow lags a bit and I'm sure it won't be a problem with only dark overlay.

Add separate delay for videos

Having a separate delay for videos would be really nice. I like my images to pop up immediately, but because my timeout is set to the lowest value, with videos I now have to click when the video is already hovering, and end up with the hovering video still playing in the reddit tab while the new youtube tab also plays the same video (the hover window doesn't close when I click the link to open the video in a new tab, which is my default for links).

Thanks!

Getting null errors for dribbble.com

Uncaught TypeError: Cannot set property 'hoverZoomSrc' of null

The hover-zoom works until you click the 'Load More...' button. Perhaps dynamically loading more photos is causing the null?

dribbble.com

feature request : gallery of ALL images

Hi !

as the title says, it would be awesome to be able to hit a key
and see all the images contained in a page shown in a grid
zoomed at 100%.
Very useful on many sites, like reddit, 4chan, or anything that
displays lists of images.

Doesn't work on Facebook after most recent update

This extension works fine on other websites (reddit, Twitter, imgur, etc), but it hardly works at all on Facebook after the most recent update. It doesn't even look like it's trying to work either (no little white box beside your cursor when you hover over a picture).

Albums not scrolling on reddit?

It seems album scroll with wheel works on all sites, but reddit.

Request: Support for Bing Images

Hello, would it be possible to add support for Bing Images? That'd be great to have in Hover Zoom+. Thanks for making/fixing this neat extension!

Hovering over an <a> tag with a base64 string in href freezes page and maxes CPU out

Click here to see the suspicious line of code

CPU Usage

Only activates on right click

Like the title says, its only working when I right click a link/image on reddit. Am I just lucky, or did something get funky in my settings? I have it on all the defaults.

Feature request: change link's color to mark as read

As advertised. It would be cool if hover-zooming an image link resulted in the immediate marking of that link as visited.

Feature request: Show timestamp/video length for videos

isue with the site streamable.com

if you hover for ½ to 1 second over a link to streamable.com the audio will keep playing even after leaving zoom and the audio loops.

feature request: possible for vine and/or twitter support on reddit?

HoverZoom+ causing flash crash on videos when AdBlock is enabled

Playing a video on independent.ie causes the webpage to crash with "Shockwave Flash isn't responding" when AdBlock is enabled. Once you click 'stop plugin' it goes back to normal but usually crashes all the other tabs video players.

Example: http://www.independent.ie/entertainment/banter/trending/son-celebrates-mothers-day-by-constantly-scaring-his-poor-irish-mammy-then-posts-the-video-online-34525541.html

Feature request: Turn off for current tab

Heya, great extension, loving it.

However, every now and then I stumble upon a page that I don't want to have this active on RIGHT NOW. I might want to do it in future, so I don't want to blacklist it or anything, I'd just like to disable the extension for everything in this tab right here.

It could also be a global toggle that I can then turn off and back on when I want to.

Regards,
Stjepan.

unable to access options on hoverzoom+

it wont let me click on any options

Why is hover zoom asking for new permissions?

I'm using hover zoom on Google Chrome, and it is asking for permissions to

• Read and modify my navigation history
• Read and modify all data in websites that I'd visited (cookies, I suppose)

Why hover zoom needs this?

Not working on wallhaven.cc

Hi, please add support for wallhaven.cc

locks up event loop once every second, causes scrolling to freeze

mac os 10.11.1 (15B42)
chrome Version 48.0.2564.103 (64-bit)

had to disable 😭

love the extension though! keep up the good work!

It's showing the wrong image on reddit.

Hover the URL in this page, it's showing the wrong image.

I noticed this in others images as well, but it's pretty rare.

Feature Request: Scroll to cycle images in gallery

The original hoverzoom extension supports going through images in an album with the scroll wheel, similar to how HoverZoom+ supports using the arrow keys to cycle through them. Scroll Wheel up/down would be a good addition to the list of hotkeys that can be set to an action.

UPDATE: Enable "use mousewheel to navigate albums" option if it's disabled.

Hoverzooming on Gfycat shows the Gif, not the webm

I think gfycat hosts two different versions of a certain video, in webm format and in gif format.

When you hover on it, it shows a reduced quality version of the link where the framerate is reduced and the color is worse.

Feature request: Disable to images above certain size

It would be great if i could disable the plugin for images above a certain size!

Feature request: touch support

currently, there's no easy way to use this with only a touchscreen.

wrong image displayed for imgur albums

The same problem is present in the original hoverzoom. I think this may have been caused by a change imgur has made

For the link http://imgur.com/a/HaSh0 hoverzoom+ will display the image http://imgur.com/HaSh0.jpg which is unrelated to the album and often a NSFW image!

Not really an issue, but a question/suggestion?

One feature I liked in Imagus/Hoverzoom that I would like to see in Hoverzoom+ is the ability to scroll through albums using the mouse wheel instead of the left/right keyboard buttons. Could you incorporate this into the code?

feature request: play youtube and instagram videos?

Check for disabled on specific site is not shown

When I disable the extension for a specific site and then open/refresh tab with the same site the icon in address bar is greyed out, but check item "Disabled for ..." is unchecked.
If I want to enable the extension again for the specific site I have to check and after that uncheck the box.

Hoverzoom won't work on .gifv files

Hoverzoom won't work on .gifv files

Hover zoom stops working after a few pages

Whenever I'm browsing stuff very often the extension will stop working until I open the options menu and press save again.

Just F5ing reddit is enough.

It might just be chrome fucking around though.

Alright, simply reinstalling chrome did the trick, I didn't expect it to work but it did, so yay.

Request: Streamable Links

Please let Hover Zoom+ work on Streamable photos/videos (http://streamable.com/)!

streamable videos have stopped working to hover over

Not working on Picasa Web Albums and Google+ any more

It looks like Google recently made some changes to image URLs and Hover Zoom+ has stopped working since then. Any chance of a fix for this issue? Thanks in advance!

Twitter not working

I got this error when browsing twitter :

Error in event handler for (unknown): TypeError: Cannot set property 'hoverZoomSrc' of undefined

In twitter.js:l26, img.data() is null. I don't know which element it's trying to access but it must have been changed.

Request: gyazo

You should add compatibility for Gyazo.

Hover Zoom+ activates even when my action key isn't pressed

I have chosen Ctrl as my action key, but Hover Zoom+ just activates all the time anyways, regardless of the action key being pressed.

Fix relative image paths

Image link not correct when trying to open in new tab/window

When on a site such as saberforge, zoomed images will go to:

chrome-extension://pccckmaobkjjboncdfnnofkonhgpceea/ + location.pathname

instead of

location.host + location.pathname

when trying to open them in a new tab ('T') or window ('W').

Multiple triggering of shortcuts

Guessing this is a very trivial bug(s).

The extension interpret a key press a multiple triggers instead as a single event.

Examples:
Option "Open in new tab" with "t" opens about 5-6 new tabs.
Option "Save file" with "s" leads to Chrome warning about multiple saves.

Although I have not tried the "Gallery" option (what gallery?) I'm guessing the same result here with a dozen copies of the picture.

Even if you, of any reason, would want to have a new tab and save it as well it should be two separate events as well?

Another problem that you share:

I have not checked the current state of the API nor the source if this is hard coded and I've seen this in "pure redefine key" extensions, even one made by a Google dev, it seems that Chrome does not honor specific actions of an extension but instead overrides those with with its default.

For instance, if you define "F1" as saving, Chrome overrides this with the default action, namely "Help". Adding to this mess external programs, like download apps or the OS itself that triggers on some key combinations creates a real nice "cluster fuck" (description of the OpenSSL code).

Leaving the "safe" keys that you can/can't define, the bug in question is the propagation of the events.

All the best,
Johander

Feature request: Add a button to preload the large images

Instead of having the checkbox to always enable/disable preloading, it would be great to just press a button to preload all images on a page.

Also, after preloading it would be very useful to have a button to open the gallery :)

Not working on certain site

Works fine on other sites, but doesn't work on any images on the https://boards.4chancode.org domain. Is this just me or is it a problem with hoverzoom?
