Damn, this is complicated... and simple.  To link to a Gallery image, use the HTML IMG tags.  i.e., IMG src="/photos/administrative_images/images/19706/original.aspx" border=0. Yes, refer to your image by its aspx reference.  The software parses out the code automatically and renders the image.  A scheme designed to protect the forum from attack and other copyright abuses.

Even easier is to use the Content Selector Wizard!

To link to an external image, you have at least 2 choices:

1. Go into HTML mode and enter the IMG tag as described above with the path to your file

2. In Design mode, use the [ IMG][ /IMG] tag (without spaces). e.g.,

[ img]http://myweb.cebridge.net/g/g.stockman/forum.equis/discovery.jpg[ /img] (without spaces)
