I'll close it, but I want you to know that I put a notice on my website that those pages have been taking your images without permission.

As a graphic artist, I know how frustrating it is for people to take your works and pass them off as theirs. That's part of the reason why I take SOOOOOO many screenshots myself.. and when downloading from a site, I make sure that a) it's either ok to download stuff, or I get all the information I need to credit the people on my credits page.
