When you start a new post. If you click on the insert image icon. (you have to know the address on the web where your picture is stored) Just fill in tha address and your picture will come out as a link like this.
SORRY, I had to use a picture of Rob but I am sure he will be over here soon enough
or like this not sure why one is a link and the other shows the picture but atleast you can see the picture either way.
