Believe it or not, Plex. It's a truly mediocre photo organizer, with glaring missing features, but because I already have a Plex server - it's zero marginal work aside from just dropping the photos in a folder on the NAS running it.

I use FileBrowser to autosync the photos off my phone, and family can easily access them because they already know how to use Plex. The fact that there is a client for every device I have ever used is icing on the cake.

If you have a plex server, obviously a very big if, worth investigating just turning it on for a folder of files since it doesnt write to the images itself by default.

Seconding plex. I was able to share photos with family, even grandparents, by giving them access to our plex share.

I always thought Serviio was a much better option than Plex, and has the benefit of working much better with any DLNA client.

I thought they removed this functionality awhile ago. It appears I am mistaken.

They have made it clear it is not a focus, and killed features, but that all seemed in the interest of making it something that continued to function without much work on their end. Which seems fair enough.
