I do not believe the parents can do much that is effective. It is legal to take photos of anyone in public. This applies to minors, unless the photos include nudity or sexual activity. As for posting, if the posting is part of a commercial they could sue for the value of the image used in the commercial. If it is not used for profit I do not see what the parents could do, other than complain to the school board.
