Actually, I believe that Brandon would rather have someone other than ChiefDelphi host the image you want to post in a thread.
If you know the URL of an image you want to post in a given thread (I'll use the Google logo, located at
http://www.google.com/images/logo.gif ), you can use VBB's built-in IMG tag ( "IMG" with square brackets around it) to indicate that you want to have a specific URL displayed as an image.
[img]http://www.google.com/images/logo.gif[/img]
The effect of using that would be this:
Hope this helps...
