basically put the photos on photobucket, copy and past the "IMG" of the photo, its located in one of the 3 boxes below each photo in your album on PB.
Then start a thread like usual, then click the IMG button located above the post text you are writing, then paste it automatically put the IMG link into the text body, then you can repeat the process as needed.
I always hit the "preview reply" button at the bottom before submitting and then you can verify it and not look like a rookie posting a bunch of empty replys.
