The plugins site is currently in development.
We've been looking to provide a higher-quality, spam-free experience at the plugins site for some time, and a major error on our part forced us to shut down the current site before we could put the new one in place. We are developing a new site, and you can follow along with its development on GitHub. For more information about this transition, including steps you can take as a plugin author to prepare, please read our post about what's going on.
Thumbnail hover popup
This plugin will display a thumbnail’s larger image like a tooltip when you hover over the thumbnail. This can be used for sites whose thumbnails and larger images have almost the exact same filenames except for one piece that changes between the two. An example is thumbnails ending with "_thumb.jpg" and large images ending with "_large.jpg". You provide the plugin the filename flags for each size and then when users hover over a thumbnail the plugin will create a tooltip and load the large image by swapping the size flags.
I originally made the plugin for Greasemonkey so I could preview larger images on certain sites without having to click to the next page. It also works great when implemented directly on a site. Example sites that use this filenaming convention are flickr, vi.sualize.us, and tinypic.
