You could put your Photobucket account on private/lock it, but that's only a so-so option. Photobucket is a bit stressful for my computer so I looked for an alternate site and found http://mynetimages.com. You can set your albums so no one but you can see/has access to them. I've been using it for close to a year now and have yet to have any trouble with it. Though, my only compliant is that you can't upload really large images to it (I think 2,000+ kb), but if you lock your Photobucket, you can just upload bigger images there.
