How do I get a desktop slideshow with both monitors having the same thing displayed?

I don't want my monitors displaying two different pictures. I want them to be the same when I have a slideshow going.

I don't want to span my images across both monitors. If I have a sunset image on monitor 1 the same image should be displayed on monitor 2.

And when it goes to the next picture, both monitors switch to the same picture at the same time.

Just like the desktop slideshow windows 7.
