jason, go to photobucket http://www.photobucket.com and sign up.
Open an album and upload the pictures you want ot post to that album. Threre is a size restriction, but you can do this either in Piant Shop pro or photoshop or such before hand or you can re-size on the site.
Once the images you want are on the photobucket site and ready to post, start your topic in FSM.
IN photobucket, under your images are three tags: URL, TAG and IMG.
Highlight all the text in the IMG box ( including the [img and [/img]] bits. Copy and paste this text to yur post for FSM.
Before you actually post he message, you can do a preview, to check it is all working. If it is, you'll see your pictures. If not, you'll just get text or a small white box with a red X thru it.
Try it and let me know how you get on.
