I also knew nothing about self hosting, but wanted to move away from Google photos, and that eventually led me towards self-hosting and immich.

Most people recommend using something like Tailscale so you can access your server from anywhere. That wouldn’t necessarily work for me, because I wanted to be able to share links to pics and videos with friends/family who wouldnt be a part of my Tailscale network.

I ended up purchasing a cheap domain, and using cloudflare to allow me to share links broadly. (Because my family deserves better quality videos of my adorable children than the compressed crap that comes through in a group message between iOS and android. I have tried SO hard to convince them to move our group chat do a different platform but I have failed.). It’s probably ill-advised for somebody who knows as little as I do to go this route, but I’m filled with the un-earned confidence of a middle-aged white man.
