Photobucket can also resize your pictures automaticly when they are uploaded. Watch out for that. Bit of a bummer if you are "backing up" the original photo there.
Photo bucket are also one of the few photo server co, that can find your account when you have lost your pass word.
Having not used it in a very long time, I needed to get on again for my boat build pictures. Pass word!!! After two days I contacted them, filled out a form, sent a mail and they found the account based on the content!!!
Never use anything else, never had spam from them either, (as far as I am aware).
