what would you do? possible copyright infringement

[Rich]

I wouldn't change a thing on their server.

It's pretty safe to assume that he can prove he did the work, the question is can he prove they don't have the right to use it.

Actually, if he persues this in court, it will be THEIR responsibility to prove that they DO have the right to use it. He is filing a copyright infringement lawsuit. His gripe will be simple: They are using MY material, which I can prove, and claiming it as their own. That IS the essence of infringement. They are claiming that HIS work is their own. He can sue for up to $50,000 I believe seeing as they are claiming they created the style.

Since there is no contract, and he can prove he created the graphics and design, they are...without a doubt....violating the copyright laws and they will not be able to prove otherwise. It would not be a "he said she said" scenario because he CAN prove he made everything.
