I kinda fell on this today. Looks REALLY nice in the way it works: TinEye Reverse Image Search Basically, this is a search engine that is slowly indexing pictures on the net (about 3 million a day) and is incredibly fast in returning answers to if your pic was stolen by someone. Al fellow wedding photographer found someone that stole his pic and he resolved it within 25 minutes. Issue resolved amicably to boot! Anyways, check it out and let me know what you think. This is still in beta, but man, I am genuinely impressed.
