Its good to have photobucket and Iceshanty open at the same time...
Go to the place where you want your pictures posted and click "start new topic" or "reply"
Once you get the message window, you type whatever descriptive words you want, then hit enter
Now go back to photobucket and copy and paste the bottom "IMG" link from the picture on photobucket, to your message on IS. Once you have that pictures' code in the message you can hit enter and put another picture in that same message!
P.S. -- you can click preview to see if it is going to work
