TinEye is an image search engine. You give TinEye an image and it'll find it on the web for you. TinEye analyzes image attributes and compares fingerprints of every single image in the TinEye Search Index. However, keep in mind that TinEye is a new Web search engine and they didn't have the time to index all the images on the Web yet. I found over 500 sites containing variations of the image.

TinEye is the first image search engine on the web to use image identification technology. Given an image to search for, TinEye tells you where and how that image appears all over the web — even if it has been modified.

Just as you are familiar with entering text in a regular search engine such as Google to find web pages that contain that text, TinEye lets you submit an image to find web pages that contain that image.

Every day TinEye's spiders crawl the web for additional images. Using sophisticated pattern recognition algorithms, TinEye creates a unique and compact digital signature or 'fingerprint' for each one and adds it to the index.
