hi Lou
just had a look at my profile. You need to click on the Profile tab on front page. Then on the right hand side you will see Forum Profile Information. Click on that, then choose "I will upload my own picture."
Next to that is Browse... button. Click there, then find the pic you want on your own computer. Once it appears in the text box, go to the bottom of the page and click Change Profile. If I'm right my new pic is now online... If not, then sorry - i can't either!
very best wishes
Phil
