Show Wallpaper when Computer Locked?

Windows 7 Professional

I'm curious if there is any way to show the wallpaper / desktop background when the computer is locked (windows key + L)? Currently it is the generic windows blue background with my User Pic and the box to enter my password to unlock. It would be kinda nice if I could replace the generic blue background with my desktop background.

I kinda doubt this is do-able, but if there is a setting I'm not aware of, would appreciate the tip.

 

Here you go. It won't show the desktop icons but you can make any picture you want the logon screen background. It has to fit certain requirements though, the one I'm linking does all of it for you.

the one blaze linked to is good, and you can also use LogonStudio if you want (they do the same thing): Stardock.com - Your Edge In Software

or, you can do it manually if you want: How to Customize/Change Windows 7 Logon Background Wallpaper Screen
