TinEye is a reverse image searcher.This engine works using image comparison technology instead of keywords like google* . Its still in beta so the search index is expanding however in even in its incomplete state I found it to be a very useful utilityA powerful tool
Useful for:
- Finding out where an image came from, or get more information about it
- Researching or tracking the appearance of an image online
- Finding 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
