Profile picture at center of lock screen
How can I remove (not change) my profile picture from the center of the screen that appears when computer boots up and the lock screen that appears when the computer has been idle for the set period of time? I don't care one way or the other if the picture shows up elsewhere—I just would like it not to appear at the center of the picture I've put on those screens.
I'm able to edit the profile picture, but I don't see an option in System Preferences for removing it entirely. Thanks for any suggestions.
