I am confused, are we looking at the same page? This seems like a perfectly ordinary web page when I view it. There is a photo gallery in the middle that is probably JavaScript-based, but that's working fine for me too. I clicked the zoom button and used the right and left arrows to browse through it (or swiped on my phone). I viewed it both on my phone and on my portrait mode 4K monitor, looks great on both.
I'm not disputing what you saw, just puzzled that we seem to be seeing two different things.
I wonder if the URL was changed or something? This is the one I'm looking at:
