It would be nice (and I'm looking for somewhere to move all my Flickr photos), but it massively increases the resources required at the back end. Storing a lifetime's worth of typed text is maybe tens or hundreds of megabytes. Many people will generate that much data as photos in an afternoon.

I'm also yet to find the perfect photos app. It needs to have:

- self hosted front end with a simple management interface for organising photos into albums, uploading, setting permissions - simple security so you can share only with the people you want to share with, especially simple for older relatives - backend storage should be any cloud hosting system such as on AWS S3, but the data shouldn't be accessible to any one publicly, except via the application, and ideally encrypted at rest.

I really like Google Photos for it's excellent search capabilities. Being able to search for photos with my dog or from a time or specific places is fantastic.

Same here. I'd love a self-hosted Flickr. All the ones I've tried don't even come close. I like Smugmug as far as layout/features and use it too, just wish I could self host it.
