Hi Moto Modernist,
In the form to post your message, you will find three fields called "associated web images" that you can use to post images.
Just post the simple url of your image in these fields.
example: 
If you dont have your own website, there are many sites that can host your images very easily.
Here are a few:
Flickr: http://flickr.com (free)
Photobucket: http://photobucket.com (free)
Picasa: http://picasa.google.com (windows only, free)
.mac: http://www.mac.com (mac only, fee applicable)
Hope this helps.
