Just checking: The [img] coding you're talking about is in the final post, right? You're supposed to see it when you're writing/editing the post. The picture only appears once you've actually posted.
So, for example, if I wrote
[img]http://www.lcficmbs.com/ubb/loisclark.gif[/img]
I'd see that when I was writing the post, or when I went back to edit it.
When I actually posted it, though, you'd see this in my message:
(To make the first one show up as text, I used a [code] tag to let the boards know I wanted the text to appear rather than processing the code. The quote-like box is a side effect of the [code] tag.)
Is that clear?
