Replying to Block Images?

OK so I am super sick of kids posting those damn pictures of like facepalm and cats and stupid shit. It's bad to the point where I am embarrassed to be on NS in class in case someone looks on my comp and sees these retarded pictures.

My idea is to have a selection in your account where you can have images turned on or off. If it was turned off then they would just appear as links. Would this be hard to do?

It is really nice being able to have relevant pics and youtube vids in the forums. I just can't stand those dumb pics. Having strict rules bannning them would be sweet but that's not gonna happen.
