Louis, I'm not sure what your line of thought is. Yes, that was the whole point of the photos - to show an alleged assassin holding guns up and Marxist literature. If we're to believe Marina, she was in a rush and didn't really care about taking these photos as she had other things to "attend" to. As Jerry said, all photos look almost as if they were taken on a tripod, perfectly framed with very little difference in the overall layout.
It's important, too, to take Oswald at his word. He did say that the photos were fake, that he could show how they were fake, and he never got an opportunity to show this. His lawyer never got that chance too because he was refused representation even after his death. Even Jeffrey Epstein has been given the benefit of the doubt upon his own death.
