It's nice you finally decided to add a pic to your profile :)
Here's what you need to do: First, make sure you're logged in to your account then from the Memberâ€™s Homepage, please click on the Profile link from the second level of the red menu bar at the top.
Scroll down the Edit Profile page until you find the field you wish to change. In this case, you'd like to add your photo so go to Upload Avatar, click on browse to search for a pic you like and then click the Save Changes button from the bottom of the page.
This should do the trick! Looking forward to your pic :)
