As most of you know, Photobucket's TOS change disallowing hotlinking without forking over $400/yr has caused a lot of pics to be inaccessible. If you still haven't migrated to something else, links to images on PB can be repaired by adding (without the quote marks) "~original" just before the [/IMG] string at the end of each image link.
For example:
...foldername/picname.jpg[/IMG]
Becomes:
...foldername/picname.jpg~original[/IMG]
Hard to say how long this will work before PB finds out and disables it.
