Wide, Photobucket no longer allow free third party image hosting, that's why your pictures can't be seen.
You either need to upgrade your Photobucket account at an exorbitant cost of USA $399 (
) or switch to an alternative to Photobucket.
Not surprisingly, I don't know of any one who's paid Photobucket to upgrade. Postimage (
www.postimages.org) seems to be a popular choice, or Imgur.
