Displaying wallpaper when desktop is locked in Windows 7

I've googled this a bit, but have yet to find anything.

I have 2 monitors. when I lock my screen via win+L, it turns 1 of them off/black, and the other one is the win 7 login screen.

I would like to keep my current wallpaper as the background and on the two monitors if possible when the pc is locked.
