TinEye Image Search Engine

On the way to work today, I was listening to a podcast from The Focus Ring. This is a group of photographers/podcasters all around the world that speak on photography. At the end of the broadcast, each photographer gets to bring forward a tip-of-the-month. Boris Nienke, from the German speaking nSonic podcast, brought up TinEye, a web site that will search the Internet for an image that you feed it. It looks like it does a pretty good job finding manipulated copies of the image too. I am off to check it out a bit now.
