Image Based Search Engine - Tineye.com

At last, an image based search engine that doesn't search by words - yes, it truly searches by image.

Toronto, Ontario-based Idée inc. has authorized over 12,000 beta testers for Tineye, with a waiting list that grows longer by the day according to CEO Leila Boujnane. Idée's goal with Tineye is quite simple: to be the image search engine. And although you'll never hear anyone from any company (think Google and Photoshop) officially admit it due to trademark diminishment concerns, it's a safe bet that Tineye is secretly hoping to be "verbed" in the image-search space: "Can you Tineye yesterday's lead photo to see which blogs picked it up?" And there's already a Firefox extension, making it easy as a right-click to launch a Tineye image search.
Well I got all this from a great article in PopPhoto.com, so read it there.

But I went to have a look at Tineye and registered as a beta tester and installed the Firefox plugin. Now all I need to do is right click on any image and tell it to "fetch".

OK at the moment the database isn't very big, but imagine what it will be like in a year or so - just imagine the potential for an image based search engine?
