JIM; If someone puts a work of art, a manuscript, anything that can be protected by copyright but fails to copyright it, how has the second used violated anything? I'm very ignorant in this area of the law, but I'm not sure that a person who has pics that can be accessed has any legal rights of protection to the scans unless the scans are copyrigtable--if they can be copyrighted. So to answer a rhetorical question you posed: "If someone publishes a book and offers it for sale in a store, does that mean any other person can just copy and use it for commercial purposes?" The answer, I believe, is "yes" unless the author had taken steps to protect the manuscipt. Is that incorrect?
