Trying to take the pictures out of a screensaver

[Thresh]

I installed a screensaver and want to use some of the pics it uses as a slideshow as wallpaper. The installation file is .scr. Is there anyway I can open this up to view it's pictures? I already tried the obvious "Prt Scr" and Ctrl+V technique, all it does is bring it out of screensaver mode and nothing is copied. Thanks.
