These images are actually in a specific directory on the boards server. When you click on one, the s/w just puts a few special characters in the text box that are related to that image. Then, when you send or preview the message, the s/w (on the server) replaces those special characters with a link to the actual image (again, on the server). So, you never actually have to create that link yourself, the s/w does it for you.
The point is, you need to actually send the image itself or a link to one if you want anyone to see it when not using this board. If you have space at your ISP, you can upload some images there. I think
Gary S has a lot of these images (most of which he designed himself) at his site. And I think he allows people to link to them. OTOH, I may be completely crazy and have misled you in your quest for glory and enlightenment!
