Photos will always have a meaning to someone. While often people don't agree on the meaning and the original photographer didn't mean for it to come across that way, as long as the message isn't inappropriate, I think people should accept it.
.. and that sounds like a load of crap. Umm. Lemme start again.

A photo doesn't have to have meaning behind it, but usually people will place significance on it anyway. (Especially if they're an English teacher and you're doing film studies. I'm sure that the director didn't mean that.. aww, c'mon, now you're just ********ting...)
