To change the boot login background, do the following:
1. cd /System/Library/Framewoorks/ApKit.framework/Versions/C/Resources
2. cp NSTexturedFullScreenBackgroundColor.png NSTexturedFullScreenBackgroundColor.png.lion.orig
3. cp your_new_background.png NSTexturedFullScreenBackgroundColor.png
To screen capture the login page, do the following:
1. sudo screen -m -d bash -c "sleep 60; screencapture /Users/USER/Desktop/login.png"
2. Logout and move your mouse cursor out of the way.
3. Wait until you hear the sound of the camera shutter.
Voila!
Have a great day!

After using the command you posted to capture the login screen, it saved to the location but whole picture is filled with black.....
If you have multiple screens, it may have captured the wrong screen. In this case, you probably want to make sure there is only one display. For example, I have three displays and had to disconnect the external displays to get the capture to capture the correct screen.
Also, it may have snapped the screen capture before the login screen came up. Listen for the snap sound of the screen capture app.
Hope that helps!
