For some time now I have been frustrated by not being able to change my Login Image to be the same as my Logout image. The Logout image is defined by a .face.icon png file in the home directory.
I copied the .face file to face. I then used System Settings > Users and then clicked on the user Image followed by Choose File. I then selected the face file. Voila, I now have the same image for Login and Logout.
