TinEye Image Search Engine

Developed by Idee, the TinEye search engine allows users to search by uploading a picture rather than typing in a keyword. The SE then conducts a pixel by pixel search across the Internet, flagging all instances of that image even if it's been cropped, merged or digitally altered in some way. SE Uses, copyright enforcement of course, but TinEye can also be used to identify image creators and publishers to provide attribution.

The SE will be coming out of private beta this month but in the meantime, you can read the TinEye FAQ and this PC Pro article, Visual search engine is photographer's best friend. Hat tip to Slashdot. [JH]
