From Photobucket, find your picture, under your picture are four options, click on the bottom option (IMG Code) and highlight the whole thing. Once it's highlighted,double click on it, and hit copy. Now simply go to the Dis board thread you want, and Paste that IMG Code on the thread. That should be all you need to do, but you might want to "preview" your post before submitting it, to make sure it comes out OK, if it does, go ahead and submit it.
