I’d first recommend that you think about what you need.

What do you need? Do you want a safe space to back up your photos & videos from your phone? Or maybe a way to stream your movies, series and/or music in a cheap way?

Once you figure out what you want to host, you can look into which program can fulfill your needs. Check out the awesome-selfhosted list for a HUGE amount of services you could host.

You could try making a symlink, so that there is a ‘file’ in the Nextcloud directory which points to the Immich gallery, although I’m not sure how good it truly works.

Does this also apply to linuxserver/nextcloud image? Because that’s what I’m using.

I’m using Calibre-Web
