In order to get them to show up "inline" instead of attachments, you have to host them externally and link to them from their hosted site.
Now remember, this is only to demonstrate, so remove all the spaces (that prevent it from actually reading the code):
[i m g] http :// www . yourdomainnamehere . com / nameofthefolderthepictureisin / nameofthepicture.jpg [ / i m g ]
So, here's the example:
This image is my interpretation on the theme "hot" - this was a performance by some of the performers from Circque du Soleil (yes, the world-famous troupe) as a benefit for the Pets Lifeline of Sonoma Valley. The Black Cat Caberet was AMAZING, and raised over $80,000 for the animal rescue organization. I was privileged enough to photograph this event (as a volunteer) and see the amazing show.
This is hosted the same place my website is hosted, I have a folder for this forum, so I know what I'm hosting and where, and the name of the image that I'm displaying.
If you right click on your mouse, it should give you the option of displaying the image in a new window - and the url will tell you where that image came from.
