It doesn't fix/edit the links for other users but makes the broken images work in your browser? I'm guessing it just spoofs the referer header in the browser's request to retrieve the image so photobucket thinks you are viewing the image from their website. If the hack becomes too common, I'm sure photobucket will find another way to block it.
Looking at the reviews, it looks like the add-on used to alter Amazon links for the developer to collect referral fees for your purchases. Be wary of 3rd party plugins.
