CB Connect isn't bringing through the avatar image when a new member registers or existing member links. I thought that was automatic. What settings/permissions might I have missed?

What permissions are required for this to work on the Facebook->Application tab?
I don't think I need anything in Facebook->Registrtion->Fields. When I first installed i did try to use image url mapped to profile image. I now know that this was wrong. I have since unistalled the plug-in and set it up again without messing with image mapping, but still no luck getting the image to come through

Your help is appreciated.

FIXED: I didn't have GD2 image library properly installed. If others have this issue, check that the images tab in CB configuration shows any errors with image library.
