I've just started a temp booking and the boss wanted to test his new camera?

out on us (me and the lady I'll be covering for who goes on holiday for 2 weeks from tomorrow). I thought the photo would only include her,but it includes me and I don't like that. He didn't ask my permission to take one of me. The thing is, I don't know what he's going to do with the photo. Should I just brush this off or what?
