Yes, but a couple things. It's just one more step that I feel is unnecessary. I could just re-size them on my computer if I wanted to take extra steps. The other problem with image hosting sites is your pictures end up disappearing after a period of time.
The plus side is you own your content, but that's never been an issue for me.
Your pictures don't disappear after a period of time with photobucket. The reason they disappear, unless I'm mistaken, is because you're only given a certain amount of space with the free version and people delete the pictures in the photobucket account which causes the broken link.
It is extra steps, but for me, it's worth it for the added flexibility the image hosting sites provide, plus when I run out of room I just create a new e-mail address and in turn a new photobucket account.
My advice would be to go to the site suggestions area/thread and suggest that they add increased picture storage as part of the premium membership (I don't think it currently is but, again, I could be mistaken).
