I use photobucket for my online pix and have not had any problems with it yet, and it's been over a year.

When I download the pix from my camera I first put them on a CD, then check that CD to be sure it got all the pix. Then I delete my camera chip, not before! Then after that I copy the disk to my cpu. My pix on photobucket are only copies, if they all dissaperared it would be an irritant but not detrimental since I have back ups. I won't ever, rely on anything online to be the sole storage of my pix, they are too valuable to me. As it is I'm thinking of getting a second removable hard drive for additional back up of my pix just in case.
