Amphi Photos is a free and open-source, cross-platform photo gallery.

It supports all popular image and video formats — no conversion required.
You can organize your photos into albums and write personal notes directly on each photo.
Once your gallery is set up, you can sync it across devices via a self-hosted server, letting you view your photos anywhere.

If you already use Amphi Notes or Amphi Music, your notes and music library can also be synced through the same server — keeping all your Amphi apps connected seamlessly.
