The implemented Photo Sphere Viewer
is made by Jérémy Heleine
. The image bounds of a slide have been set to 2560x1440 and folder 'panslides' is not used. There are no previews, because check-mark 'Expand Spherical panorama automatically' has been checked. See here
for the same album with previews and the use of the 'panslides' folder.
The 2nd panorama is displayed in the Marzipano viewer
, see here
for the recipe how to make that page.
