Find Pictures in Web? [closed]

I want to have a tool what is able to find my pictures in web.

That means I have pictures with a watermark from me inside the picture and I need to be able to scan webpages (and all pictures in it) and see if my picture is online on this webpage.

Background is, that someone used my picture (with a watermark from m开发者_开发知识库e) and win a price with it!

To get all pictures from a specific site is very easy. The question is, how can I look inside a picture for my watermark?

You want to scan the entire internet looking for pictures which look like yours? That's a lot of work, why not use something like TinyEye to do the hard work for you? I think you've really underestimated what's involved in doing it yourself.
