Reverse Image Search Site Covers 9 Billion Photos [1]

If you like trawling the internet in search of interesting things, here's a fascinating web site that will help your research significantly. Tin Eye (www.tineye.com [3]) is a reverse image search facility. Upload a picture, or paste in the URL of an image on an existing site, and Tin Eye will tell you where else that image has been used.

If you've ever uploaded some of your own photos to a web site, and you want to find out whether anyone else has "borrowed" your images to use for their own purposes, then this site will help you find out.
