MUI ImageList loads images one after another, which leads to loading all
images even with loading=lazy. Maybe it depends on the order in which
images are loaded, but this issue never arose with react-photo-album
FolderGallery always displays folder icons in the same way and simply
positions the image to cover the space available. This circumvents the
issue of different aspect ratios of images.
Only covers simple cases. Administrator is responsible to secure that
the user that runs the webserver is not allowed to access files that
are not within the shared folder.
Add jest to picture-gallery-server
