Avatars stored outside domain.

[WizyWyg]

Want to host avatars on a remote server (outside my domain)
Want Vbulletin via user cp options to get a list of avatars from the remote server and list them as they normally do if I had stored the avatars in the DB.
Instead of posting the location of the avatar from the DB, I need the script to post the URL to the actual avatar on the remote server and place it in the USERS custom avatar field for them (so if they choose an avatar from the list and on my server its http://myremoteserver.com.ips/avatar.gif, need that URL to be placed in the URL field under Custom Avatar)
Then when user presses submit, the AVATAR is now their avatar.
