I just published a pigallery2-metadata-editor

Although PiGallery2 is designed as a read-only photo gallery (a wise decision for safety), I often find myself wanting to make quick adjustments to photo and video metadata – especially when viewing pictures on the web.

For example, I use the F-Stop Gallery app on Android to organize and tag my photos and videos directly on the phone. F-Stop uses a custom XMP tag (XMP-fstop:Favorite) to mark favorites. While this works great on mobile, I wanted a way to adjust this Favorite tag (as well as Ratings and Tags) directly while browsing photos and videos in PiGallery2 – without having to go back to the phone.

That's why I've just published pigallery2-metadata-editor!

Key Benefits:

• Tag or rate photos and videos directly in your browser while viewing them in PiGallery2.
• Immediate visual updates in PiGallery2 after saving metadata – no restart or rescan necessary.
• Modified files synced back to mobile (e.g. F-Stop) show updated tags instantly.
• Safe: all changes are performed via exiftool, optionally with a backup created.
• This setup leaves the PiGallery2 source completely untouched, so you benefit from future updates without merge conflicts.
