This is a panorama presented as a scrolling video so it can all fit onto a web page and still have a reasonable height. I learned how do do this from Derrick Story at The Digital Story

"These movies are easy to create. 

Start in Photos for macOS. 

Click on the plus sign that appears when you mouseover My Projects in the Sidebar. 

Name your presentation. 

Then click on the Add Photos button (+) at the bottom where the thumbnails are displayed. 

Mix in a few standard images with your panoramas, and arrange them in the order that you want. 

Finally, apply the Ken Burns theme, and play. You will be delighted with the presentation.

You can export the slideshow as an HD video, then share on Vimeo, YouTube, Facebook, and anywhere else you display your stuff."
