The SCLogin module can load the profile picture from JomSocial, Kunena, EasySocial, Community Builder and one or two others I can't think of right now. If you have JFBConnect installed for social network integration, the SCLogin module can also show the user's social avatar.
I hope that helps answer your question, but if you can't get the avatar to show, let me know what extension you're using that you want to pull the avatar from.
Thanks,
Alex
