Looking for a self hosted alternative to Flickr

Hey everyone, I'm hoping to find a self hosted and hopefully FOSS alternative to flickr for photo organization and viewing

The sharing with friends part isn't important

What we're looking for is a way to store collections of photos, organized and viewable the same way as Flickr

This person takes a ton of photos all the time but they want a place to store the best/only the highlights/their favourites, organized into albums by destination/location/vacation and most importantly easily viewable to reminisce about the good times

They used to use Flickr for this until it wasn't free anymore
