"There is no law that requires Yahoo! to sit back idly while Disney, Paramount, Anne Geddes, and many, many, many private artists have their work hacked up and passed around. They are perfectly aware of what goes on in those groups. They just haven't got the resources or the interest in monitoring them and they don't care unless a copyright holder threatens to sue them." This is very unfair to Yahoo. Yahoo is not your policeman, you are. As the copyright holder it is YOUR responsibility to ferret out those who are stealing your images.
