Remember what I said - it's your photobucket account. So when you click on it (even from the forum page) Photobucket is recognizing your IP address and lets you into your album. But, so long as you have the album set to private, it won't let me or anybody else in because our IP address is not the one used to set up the album.

When I click on the video that I posted above Photobucket gives me the previous/forward option because it's my account. But if you click on it you won't get that option. Just make sure you've set your album to private and saved the account setting.
