OK. When you register with photobucket, you create an account with a password. Then you create an album. All free.

When you search for a particular type of picture, if you find one you like, click on it and bring it up full size and that grey bar pops up and says "copy to my album". Click that. Go through the process. Once you copy it to your album, it becomes YOUR photo. So even if the old owner deletes their account, it is still your photo since it's the copy that's in YOUR album now.

So when you decide to use it, it's your photo and it won't say that annoying message.
