Janz,
JFBConnect doesn't store and display the image for the user. We simply hand the image off to JomSocial, or one of the other 3rd party profile extensions we support, and tell them to store it.
The Joomla profile plugin also doesn't have a way to store avatars (that I'm aware of) or we'd support that.
In short, you'll need to use JomSocial or another one of the extensions we integrate with to store the avatar and user's profile data.
I hope that helps explain, but if there's more information you need, just let us know.
Thanks,
Alex
