sounds like you're pissed off cause someone stole your picture or something?
ok, the bad news is that there is really no way to stop people taking your pictures. if you dont want the pic taken by anyone, keep it to yourself and dont put it in msn...
once you do put it in msn, it can be take, for example with the
display pictures stealer program or even simply just copying from the screen.
like felu said, just remove it
