Congrats for figuring out photobucket! It's taken me weeks!
You can always see whether it's worked if you click "preview post" instead of "submit reply" under each post on here. It's worth doing when you post a lot of pictures!
You can also use photobucket for editing - like resizing for avatars, cropping, decorating your pictures with writing or symbols; all found in "edit".
I love your picture!
