TinEye is a cool reverse image search engine. It lets you take an image and search for it on the web, even finding uncropped, expanded, or unwatermarked versions of the image. Sadly, while TinEye provides plugins for both Firefox and Chrome, they don’t provide one for Safari. Because of this, I have written my own extension. Just install it, then right-click on any image and you should see “Search Image on TinEye”. You can get it here.
Update: I played around for a few more hours and got something much better. It’s still fragile, but not nearly so much as before, and it restores the fade effect for all the google content. Same download link as before.
Update 2: Looks like Google fixed their homepage sometime this morning, so this extension is now officially obsolete. I will continue to host the download if anybody is interested in the code.
