Tineye.com is a very interesting and neat image search engine, what makes it unique it's that you can upload or link to an image and find out where the image came from, if there are altered versions out there, if an image appears in another image, if there are higher resolutions available, Etc. You can get an example of how the service works by visiting the cool searches section of the site, later you can try the service yourself and i am pretty sure you will be impressed, i sure was.
