Whoops! It looks like you accidentally blocked images from Photobucket in your Firefox settings. Don't worry, it's easy to fix: In Firefox, click Tools > Options. Choose the Content tab. Make sure that the check box next to Load Images Automatically is checked. Click on Exceptions. If there are Photobucket URLs listed here, and they are designated as Blocked, click the button to Remove Site. Add Photobucket.com back into the list, under Allow. That should do it!
