The icon or small image associated with both account under system preferences that is shown at boot up. Apple's standards are things like a butterfly, dragonfly, etc.
Oh very good.
Thank you for the update.
May I please, remote into your Mac so that I can better help you resolve this problem?
If you do not wish for me to do so, I will not.
Other than a screen snapshot is there a way to duplicate or copy the image or not?
The only way to copy it is by using a screenshot.
