Can't figure out

[dadster]

I'm working on KDM log-in themes and want to know how to get a snapshot of the log in screen.       That way I could display a pic instead of users having to install the theme just to see it.   Any help would be appreciated.

Ok after more research  I think the easiest way is to run the OS in virtaulbox or other vm and take a ksnapshot of the login screen.
