I hope Mary Jane is OK with you posting a picture of her. Did you ask first?
I don't think that matters. If Mary Jane wants her picture posted, she will post it herself. I removed the link in Yaraslau's post.
And that pretty much goes for pictures of everyone. The only way we can be sure that someone has permission to post a picture is if they post their own.
As for the reaction to the situation (omg a girl, post her picture everywhere and creepily tell her how cute she is), it's borderline harassment. I haven't been keeping up with this thread on a regular basis, because I assumed that this was one of the few threads on the forum that can take care of itself. Apparently I was wrong.
It goes without saying that your fellow forum members should be treated with respect... but I suppose I have to say it now. And if I hear one word from anyone in the future about being harassed, I'll start handing out bannings. It's not cool.
