yes mate but you need to add a link to them from the photobucket site, basically once you have signed up to photobucket and you then need to uploaded your pictures. Once you have done this you will see your picture with 3 bits of text underneath.
URL
TAG
IMG
if you copy the text next to the IMG and then paste it into a post that picture will appear in the post.
Try to keep the file size down to a smallish size tho mate!
If you need any more help let me know
