Man Lemmy is so much better than Reddit.
Yeah, seems like Immich is kind if taking over. It really is an excellent one stop solution for automated multi-user backup. Ive been using it for a few months and its solid.
The other option that I really like is a combination of software: Nextcloud + Les Pas. Nextcloud is the server where images are stored in a flat folder system, and Les Pas is an android photo album app that organizes and manages the albums. Its super nice and has some really advanced organization features. Worth checking out if you want to use nextcloud as the storage server.
Picsur might be a good option, it was designed to be a self-hosted replacement for imgur. Here is the github:
For your use case I would definitely recommend Immich. It has a “partner sharing” feature that allows you to view your partners photos from your account while still maintaining separate archives. You can then download or add to albums from there. Immich has been fantastic for my family because it supports android and iOS (being as I can’t get some members off Apple products.)
Here’s the description of the feature. Sorry it’s a Reddit post, that’s the only place I could find the developers summary of the update.
