GUI to Change the Login Screen Wallpaper Image on Snow Leopard

"There's this that will match the login screen to the current wallpaper.

And this to set it to the image you like.

I haven't tried any of those, I did with the CLI, too."

"Here is an easy way to change the login background on Mac OS X 10.5 and later in three steps:

Choose a picture you like and save it as DefaultDesktop_Org in your Pictures Folder
Press Command + Shift + G and type in: /System/Library/CoreServices
Drag the picture you saved into the ""Core Services"" folder you just opened and replace.

It really is that simple - a drag and drop."
