Is there a similar thing but for organising images? I have a bunch of image folders on my NAS but I would love it to be searchable, automatically tagged by certain criteria so I can filter them, etc. But self-hosted. I don't want to use Google Photos or Dropbox.
If you want features such as facial recognition, you might try taking a closer look at PhotoPrism/LibrePhotos. I did try them about a year ago, but in the end just went with the desktop app digiKam (https://www.digikam.org/)
I haven't used it, but stumbled across Damselfly [1].
From the About on GitHub:
> Damselfly is a server-based Photograph Management app. The goal of Damselfly is to index an extremely large collection of images, and allow easy search and retrieval of those images, using metadata such as the IPTC keyword tags, as well as the folder and file names. Damselfly includes support for object/face detection, and face-recognition.
For photos, I find Lightroom to be great. But you're still going to have to spend some time on curation, metadata, etc. if you really want things to be findable.
