If you use Chrome there is a Photobucket Hotlink Fix extension. The pictures display as intended.
The photography forums I belong to have pretty much banned photobucket. It is not an outright ban, but their service is highly frowned upon, and they strongly discourage its use.
I stopped using it when they originally locked everything up unless you paid, effectively holding users' images hostage. They did change that policy after the outrage that followed, but they never did get back to what they were. I still had images on Photobucket until recently. They sent me an email saying I was over their limit, despite the fact I was way under their limit. They then said I went over their bandwidth limits for their free accounts, despite not using the service since their initial debacle.
I was traveling at the time and told them not to worry, I would delete all my images and account when I returned, telling them why I no longer use their service, and that though I am a photographer, and gladly pay for hosting services, I would never pay for theirs after what they did. They kept sending emails saying I don't have to delete my images or account. After repeated emails detailing why myself and other photographers dislike their service, they finally understood. They won't change, and I won't go to any machinations like switching browsers to see an image hosted by Photobucket. It is my hope they go out of business.
In the end, I deleted all my images, but decided to keep the account open to simply take up space. I thought about putting a number of images, up to the limit, all with text describing why I dislike the service, but that would probably be ridiculous and not worth the effort.
