@skilled_gamer: The only thing to be careful of is that it is actually a poster that is sanctioned by a studio. You can usually tell if it has all of the credits, company name, etc and if it is from a reputable source. There have been a couple I have posted that have ended up being fan art that they did not approve. If that ever happens, you will just get an email with a cease and desist. However, if you then swap out the image once you get an email, you should have no problems!
