Want to Change your logon Screen In Leopard? See HEre
Open up the Terminal in Applications » Utilities and type in the following:
cd /System/Library/CoreServices
sudo mv DefaultDesktop.jpg DefaultDesktop_org.jpg
sudo cp /Path/to/picture/you/want/to/use/image.jpg DefaultDesktop.jpg
After the first “sudo” command, you will be asked for your password. For the last line, instead of manually typing in the path of the image you want to use, you can just drag it into the Terminal. If you were to browse to the CoreServices directory in Finder after you did this, you’d see something like this showing the new image and the renamed old one.
Here is some pic's
Any Doubt?
