Open two tabs in your browser (internet explorer). Open the relevant forum like this one in one of the tabs, - Photobucket in the other.
From inside Photobucket you just click on "IMG Code" underneath a picture, - and the "bucket" answers "copied". Then jump to the other tab where you have the forum, - insert your cursor where you want pic posted, - right click and "paste".....
Cant be much easier............
