Have you ever had people laugh at a picture of you?

My clmates are mocking this picture of me, which is posted on the blackboard along with everyone else's pictures, they say they can't even see my eyes cause they're so small and they hate my smile. And i feel like asking, Why do you care? I bet it makes them feel good about themselves. I feel bad cause no one ever did that before and not to sound vain or anything (really) but many people say i'm kinda pretty. So this is something new for sure. I'm kinda shy, so people just loove putting me down cause they think they're soo superior. I hate taking pictures cause i always feel ugly in them but hey, they don't need to rub it in my face. Should i even care? They're really putting me down.
