If you change it on another computer, does it work?

I tried searching but couldn't find anyone who had the same problem.

You could try removing the folder which stores your display pictures:

1. Exit Messenger.
2. Navigate to, backup, then delete: C:\Users\your_name\AppData\Local\Microsoft\Messenger\your_email\ObjectStore\UserTile (Vista/7 only. XP slightly different.)
3. Try Messenger again.
