Hi Rod
[img]address[/img] is the format. The address is the full url of the image. For example, your first image address is:
hxxp://i.pbase.com/o4/79/337279/1/134156370.U6Po9S4A.001.jpg
(I have munged the http to hxxp to stop it from rendering)
So if you use this format:
[img]hxxp://i.pbase.com/o4/79/337279/1/134156370.U6Po9S4A.001.jpg[/img]
Replacing the munged hxxp with http, you get this:
Note that on TSF we have auto image resizing. you can go to your user interface to change the size you see - I have mine set at 800 pix but can still click on the bar to see the image at full size.
