TinEye

by Joel Witmer

TinEye is a reverse image search engine, meaning you give it a picture and it finds that picture elsewhere on the web. If you already have the image you’re looking for why would this service be helpful? Here’s what they say:

Find out where an image came from, or get more information about it
Research or track the appearance of an image online
Find higher resolution versions of an image
Locate web pages that make use of an image you have created
Discover modified or edited versions of an image

This seems like a rather anorexic list of useful functions for what is actually a pretty cool concept. TinEye is currently in Beta, but it works as advertised.
