Thanks for the comments guys, 2) I am still none the wiser as to how to put an image up on this forum when required.OK, let's fix that. The image has to be on an accessible web server, in other words upload it to the same place your webpage lives. Hit the Img button, type the url of the image with http:// in front (note that it is case sensitive), hit the Img button again. Hit preview to make sure it works.
So in the compose window you will see something like
[code:1]
[/code:1]
with an Img tag at either end, and the result will be (hit the right mouse button and select properties on this image to see the url).
