I use netPhotoGraphics for my project called Skautská galerie (Scout gallery) - https://skautskagalerie.cz.
It is private gallery with scout photos, videos and PDFs since 1945 to the present from scout group in Žamberk (CZE). It actually contains 18 625 images and PDFs in 826 albums.
Some key features and setting used:
theme: Bootstrap
class-AnyFile - plugin for handling PDFs
favorite images and videos handling
two factor authentication for more secure user login
OpenstreetMap for showing image GPS coordinates on map
publicCMS - some pages are public, other pages are private
