First, add the pic that you want to post to your "my pictures" files.
Then go to the 'Forum' area on the cascity website.
On the far left of the profile screen
Under 'Modify Profile', click on 'Forum Profile Information' .
Then click on the radio button that says,'I will load my own picture'.
Then click on 'browse" on your profile and direct yourself to the picture.
Hope this helps ....
