I’ll admit I’ve not tried Traefik yet, but I see Caddy as being to web servers (and reverse proxies), what WireGuard is to VPNs.
It does what it needs to well, with a minimal config file. And if I learn and get comfortable with Caddy, then I know it can do anything I will ever need of a web server down the line with no need for me to ever change setup.
Yes, as @[email protected] says, just create a new user for each event you want to share photos about: ‘BeachBBQ’, ‘WeekendStay-July’ etc, then bind those user accounts to whatever folders you want to have the photos in and set the user restrictions to upload, share, but not delete for example.
I also use various FileBrowser instances, with a different subdomain pointing to them, also as a way to filter out usage as well.

could take you to a FileBrowser instance that only has access to photos from a certain friend group. Not sure how useful that would be to you, but it’s another way of controlling the data flow.
