The instructions provided above is a temporary fix that we can offer at the moment to help restore your images until we have a more concrete solution soon, as Richard mentioned.
Moving forward, we highly recommend that you use the Attachments tool within your Go Advanced option (can also be seen in your User CP), Pictures & Albums, and Gallery to host your images on our site here. I've gone ahead and increased the maximum file size to 10MB and registered (free) members have their storage attachments increased to 50MB, whereas the supporting members (sponsors, premium, lifetime) have been adjusted to unlimited attachment storage.
Furthermore, for Chrome users
we came across an extension that will enable you to see the broken images hosted from PB. Another temp fix for now (who knows how long it'll hold up) but here it is:
^Click the link and choose to add the extension to Chrome. Then, you want to go to the Extensions main page. It's located in the top right corner menu button, the one that is 3 dots. Or, you can try this link: chrome://extensions/
Find the one you just added (it's icon is the shape of a puzzle piece) and check the box that says "Allow Access to File URLs"
Clear cookies in cache, load up a page with a Photobucket link, and let us know if that worked for you.
Thank you for your patience and understanding on this matter.
