Image Overlay Firefox Extension - gHacks Tech News

Image Overlay Firefox Extension

Don't you hate those sites that open a new page whenever you click on a thumbnail to open the large version of an image that was posted on the website? It gets really annoying and it is time consuming as well as you have to go back and forth between pages, especially if you want to open more than one or two images. Firefox users can now install the greased lightbox extension with requires greasemonkey for Windows or creammonkey for macintosh and of course the Firefox web browser.

Whenever you move your mouse over a thumbnail image the large version will be loaded and displayed. You still have the option to click it and it would load as usual.

Update: The userscript has not been updated since 2009, which is an indicator that it may not be working for all sites that it has supported anymore. Firefox users who would like image zooming functionality in it again. One of the benefits of the extension, besides the fact that it is supporting a wider variety of websites and image hosts, is the fact that it can be installed in the browser right away, without having to install another extension first.

With the add-on installed, Firefox users can simply hover over a thumbnail or small image to see the larger version of the image in an overlay in the browser window. Moving the mouse cursor away from the image, or clicking with the mouse or tapping on the ESC key, hides the overlay again on the screen.

You can disable the extension for select sites in the options. Here you also find out more about hotkeys that the extension makes available and other features of it that you may want to modify or look at.

If you prefer a userscript to do the image zooming, then check out Zoom Image which you can install in Firefox and probably also in other browsers that support userscripts.

    Actually that is what I want to happen. I hate those extra windows that pop up and if I want to continue to view the page I don’t want to have to go back to it. Another reason to use firefox.
