Test for attached image in "preview"
Nope, don't see one either in preview.
Let's see if how it comes up when I post.
It shows up on the bottom left hand corner of the message as an attached file.
Now I'm going to put it in the body of the message using "img,/img". Can't use the brackets because it won't show up in the message. Can't use the same picture since it's not uploaded from a picture "provider". I'll load a picture that is hosted on my web site.

Now this will appear in the preview. My analysis of this is an attached file gets uploaded to the MadModder site and will not show in the preview. A picture embedded in the message will show up in the preview.
So it looks like we have two ways to post pictures. One is embedding them in the message if you have a host the has your pictures stored and a direct upload to MadModder if you attach it from your hard drive to MadModder. That seems to be the difference.

So, have I confused anybody?
