Nice case. Go to your pictures and find the IMG link that will look something like this but with a lot more characters: [ URL=http://s225.photobucket.com/....][ IMG]http://i225.photobucket.com/....[/IMG ][/URL ]
This is a link designed to post the picture in your post. Just copy the entire link and past it in your message. You can put as many as you want as it only counts toward your character limitation.
