This is the saddest part. Those that aren't willing to pay such a crazy fee for hotlinking images, and I would say the majority of users that need hotlinking, will just migrate to another service (and therefore this move might turn out to be more harmful for Photobucket themselves). But it doesn't solve the problem of existing hotlinked images breaking.Unfortunately even if users abandon Photobucket and move to a new provider, thousands of very useful forum posts with how-to guides, etc, are permanently destroyed.
I have never used Photobucket to host anything, and after this certainly never will.
