Full site hosting's not easy for everyone...
A bunch of people have commented that PhotoBucket's users could switch to a cheap full site host for far less money than PB's extortionate fee — while technically true, the reason a lot of those people were using PB because they lack the skills needed to host their own site. I'm fairly technically capable, wrote/hosted my own site & blog from 1996-2003, and I find modern 'tools' like C-Panel too much of a pain in the ass to bother with, so I sure wouldn't expect the less-technical crowd to deal with it.
