The Help and Rules section states that images can be posted. But they don’t post.
Here is an image in proper format:
<a href=“http://www.fostertravel.com/castan101web.jpg[/img]”>http://www.fostertravel.com/castan101web.jpg
![http://www.fostertravel.com/castan101web.jpg[/img]](http://www.fostertravel.com/castan101web.jpg%5B/img%5D){kind=link}
</a>
It just shows up as a link.
