Horizontal Scrolling - Width


I am trying to build a landing page for a website and we want to use horizontal scrolling.
I have the basic logic down and I am able to make it work.

My problem is that when I try to add more than 4 photos at 1200-1400 px wide the horizontal scrolling cuts me off at 4. I need to be able to add 13.
