I use Photobucket as an image hosting site (along with several others). Most of the images I post on the GG are hosted on PB. That said, PB has to be the worst performer in the image hosting category. I pay a yearly fee, but the service gets worse every year. Fortunately I don't rely on the PB platform as part of a business strategy. People who are hosting images for their businesses have lost a lot of money during the peak holiday season, and the site is still down.
Bottom line - If your business relies on PB, bite the bullet, take the financial hit, and move off of that platform. It will only hurt once -- versus a "death by a thousand cuts" in the future.
