Sorry went out of town for another wedding!
That sounds like such a sweet setup! I would love to see more pics
The integration we use is from phpbb. It stores an avatar type (type 1, 2 or 3) into the nuke users database and if if its type 3 then that means the file is held on our server.
Basically we copy the users pic from facebook onto our server in X location and then name it and store the name into the datatable.
So basically the code would be something like:
if (user_avatar type = 3) then avatar path = (table/nuke_bbconfig field/avatar_path)+(table/nuke_users field-user_avatar)
i.e. avatar_path is the path from the domain root (domain.com)/modules/forums/avatarpath and user_avatar is a filename user.jpg.
else no avatar needs displayed.
I have sent the login information for the ftp if that helps.
