Slides for The Cooler

As long as Im working in the Galley - I thought I should find out and see which way is the proper way of installing the slides for the cooler.
I do have a hunch but thought Id make sure which way these things should install..this is like learning a new language..
Here are a couple of pics I took this evening or should I say morning..showing the slides flat instead of on their sides..Is this the correct way or should they be on the sides instead?
or should they be like this?
