Login Window Help

Hi. I was playing around with the login window settings on my MacBook Pro trying to get the same login window setup on my iMac. On the MacBook Pro, the login window had my profile picture in a little circle (just that, no other users) and the two input blanks for my user name and password. The background of the login screen was my desktop picture (Andromeda).

I'm wondering, how do I get it set up like that again? I did something to screw it up. Currently, my login screen shows up as the grey screen, the grey apple, and the two blanks. I've tried every combination of things in the System Prefs, but I can't figure it out.

Can anyone please help me? Thank you!

 

Nevermind. I realized it's like that after you wake the computer up from being asleep.

Sorry.
