Usually can't see much with a tin eye.
Tinyeye is used to check to see if photos appear in many locations on the internet. A lack of hits is usually a good thing. That said, I am not proficient in its use and if you are new to it, I would say that you need to play with it. I have heard people claim no hits, and then next guy say they got hits on same photo. (it does seem like a really neat tool for screening purposes, screening of ladies that is.)
