Fran, you upload the avatar the same way that you would upload a picture for the forums at
www.lighthousekeepers.com/uploads YOur avatar picture has to be 75 x 75 pixels.
You then go to my profile at the top of the page
then to change my avatar and scroll to the bottom and isert the address in the box provided, same as you would for a picture.
I hope I got it right. Let's try and find out.
