I won't bother trying it out if it forces me to use chromium

It seems that your browser doesn't support the new native filesystem API, please use any Chromium 86+ based browser like Chrome, Vivaldi, Edge, etc. Notice that the API doesn't support mobile browsers at the moment.

For me everything looks kinda ok-ish except the actor who plays Luffy, don't know why I can't look at him.

If you like silly gag comedies then I can wholeheartedly recommend "The Vampire Dies in no Time" - it has me in tears laughing with every ep.

I use Nextcloud with Memories addon but I also use it for general file storage from many sources. If you only need photo sync Immich might make more sense.
