Gemrod,

On your Photobucket page, copy the link (highlight it and hit the Control and "c" buttons at the same time), then on your post when you hit the "IMG" button just put the cursor between the two [img]'s ([img]cursor goes here[/img]) and paste the link (Ctrl and "V"). That's all there is to it.

Good luck and pm if it doesn't work.
