There seems to be the issue with pulling the avatars from social services when logging in. Seems to be working alright when tested with facebook, but when logging via gmail or twitter or linkedin, it just goes wrong. We tried it with couple of accounts and all the time, in the Users section of the wp admin, user is created with avatar img src such as http://graph.facebook.com/106699394031209115871/picture or http://graph.facebook.com/55320490/picture etc instead of pulling the avatar from selected service.
Also, logging from yahoo account doesn't seem to work at all... A "Temporary Server Error pops up instead of logging in. Do you have an idea what might be the issues? Using wp 3.3.2, loginradius plugin v. 2.3, "Use Social provider avatar (if provide)" option checked, of course. :)
