Who is saying they have the rights - the school or the photographer? I would think the school doesn't have rights. Our school asks for permission at the beginning of the school year about using photos with our kids in them. We have the ability to opt out. I imagine the photographer, on the other hand, retains rights as it is their creative work. My guess is that your son would never be identified yet his photos could be used for their advertising purposes, sample portfolios, etc.
