TinEye Reverse Image Search

TinEye is an image search engine with a twist:  you provide it with an image, and it returns a list of websites utilizing that image.

I can quickly think of a few really good uses of this service:

• You have an image that you downloaded sometime in the past, but you don’t remember where you got it.
• You have found an image that would be perfect for a project, but you aren’t sure who the owner is, or what the usage terms might be.
• You are the owner of an image, and want to ensure that it isn’t being mis-appropriated by others.
• You have an image, and want to locate a site with a higher quality or different version of the image.
