Thumbnail Expander

Thumbnail Expander is a Firefox extension that temporarily displays the large version of images when you hover over thumbnails. With it, there's no need to constantly leave the current page to see full images. Check out each image quickly and easily, then move your mouse away when you're done. Try mousing over the thumbnails below to see how it works:

example image 1 example image 2

Thumbnail Expander works on dozens of sites, from Google Image Search to Wikipedia to Facebook, and also works with video links like YouTube and Google Video.

(Thumbnail Expander requires the Firefox browser to work. If you don't have it, you can download Firefox now.)
