Have you ever wanted to replace your default login background image?
If yes, here’s the solution: you can either do it manually, via apps or with terminal commands.
Leopard stores the default login background in the form of file named DefaultDesktop.jpg. This file is located inside Macintosh HD ▸ System ▸ Library ▸ CoreServices ▸ DefaultDesktop.jpg.
After you spotted the file,drag the new login background into the folder and change the filename into DefaultDesktop.jpg. Next time you log on your Mac OS X Leopard, you should get your new login background.
Apps
Desktop 2 Login

Matches the Leopard Login Screen background image to whatever the current user’s Desktop picture is. This eliminates the visual transition from the login background to the user’s background.
Loginox

Loginox is an application which lets you easily customize the login screen with a single Drag-and-Drop.
Drag a JPG image from anywhere and drop it into the main window of Loginox: a simple click on the “set new login image” button will change the login background image.
For switching back to the Leopard default login background image click on the “Reset to default” button.
Terminal
Find a wallpaper image , save it to your desktop as background.jpg, and in the Terminal enter:
sudo mv /System/Library/CoreServices/DefaultDesktop.jpg /System/Library/CoreServices/DefaultDesktop.jpg.old
You’ll have to enter your password to complete the operation.
Then, in your Desktop directory in the Terminal, type:
sudo cp background.jpg /System/Library/CoreServices/DefaultDesktop.jpg
Now, next time you log off, your login screen will have your new custom background.
To undo the operation, in the Terminal, type:
sudo cp /System/Library/CoreServices/DefaultDesktop.jpg.old /System/Library/CoreServices/DefaultDesktop.jpg
