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.
