I use NextCloud for syncing photos from my phone and sharing photo galleries with my SO. NextCloud is quite bad for viewing photos, that’s why I have the Memories plugin and app, but it’s still not perfect. I also have the Recognize plugin, but in my setup it’s been broken for a few months and I don’t have the time to fix it.

So if I replace the photo sharing functionality I could replace the NextCloud itself for file sharing with something lighter. Might even go back to SMB.
