The View More loads photos automatically from the observations (as far as I can tell) and there are only two observations of that subspecies, so very few photos show up there. The first photos you see when viewing a taxon page can be manually edited and they don’t have to come from observations. If you select a photo and click the info button on the bottom right, you can see where it comes from.
This first image is not actually from an observation, but from Wikimedia Commons.

The second photo is of an observation, but not one IDed to this subspecies, so it won’t show up in the View More. You can add photos from any observation, even ones that are different species.
Every other photo in that case either comes from an observation not IDed to this particular subspecies, or an external photo.
