Hey there, welcome to the T-Shirt Forums!
Hello Rodney, and thank you for your welcome.Rodney said:welcome!
To which pictures are you refering? If you are talking about the movie posters, they are all in what is called the PUBLIC DOMAIN, and, as thus, allowed to be used in any way you'd like. Plus, I have already spoken to CafePress about it and recieved permission.badalou said:copyright, trademark, lawsuit.. I hope you have a license to place these pictures on tee shirts because they are all owned by companies.
