Oh, you use [img*left] [/imgleft] to make things stay to the left or [img*right] [/imgright] to make things stick to the right.
You have to be careful when using it, though. Make sure the img you're using will take care of the wall of text your using and not make it go wonky. xD

There's a handbook about them and the others. I'll go get it for you ~ there's lots more there.

*edit;; Here you go, BB code for almost everything
