Pictures that were taken professionally in a Sears Studio that say copyright on the back-can they be copied?
Is that OK?
Although the matter involves a dispute among halachic authorities, you should not violate copyright law by copying the pictures in a non-authorized manner.
However, not every act of copying involves an infringement of copyright law, and if the copy is being made for private, non-commercial purposes, it is often permitted even under copyright law.
In addition, if the copy is (significantly) altered, it will not fall under copyright legislation.
Please see here where we have mentioned some of the halachic sources concerning copyright (though there is much material to note).
