What are you using as a Google photos alternative? Currently I’m using Nextcloud but I’m thinking of switching to a more dedicated solution.
I mainly need to upload photos from my device automatically, have an UI to see and classify them, albuns and sharing.
It’s been added recently, in the form of External Libraries.
External libraries do this, but fwiw when I tested Immich I ended up with a ton of missing thumbnails in my external library and there seemed to be no way to detect and repair them. That was a deal breaker for me and I went back to Photoprism. Immich looks really great though other than that.
