Hi Chris. You'll need to switch to another photo hosting site. I suggest Imgur.

Photobucket now (since July 2017) charge US$399 if you want to view your photos from a 3rd party site like a forum. It's your account, so you can still see the pictures, but no-one else can. It's ruined a lot of forums that rely heavily on having pictures. As everyone is now dropping Photobucket as a result, I'd transfer any family pictures for which you were using the site as a backup to somewhere else, as I can't see the company surviving for much longer.
