If you mean posting multiple pics in a single post, you have, first, to host them somewhere (imageshack, photobucket, tinypic, whatever).
Then, retrieve the URL location of the pic and put it between the [IMG] and [/IMG] tags, remember to put the FULL url, comprehensive of the "http" prefix.
Put as many IMG tags as you need into a single post to post as many pics as you like.
