PiGallery2 turns any mounted folder of images and home videos into a high-speed web gallery without modifying your raw files or forcing migration into a database silo. The server scans directories in read-only mode, keeping folder structures intact while generating responsive previews with hardware-accelerated Sharp processing. Users can inspect detailed camera EXIF metadata, toggle custom full-screen lightboxes with swipe gesture navigation, and stream high-definition MP4 or WebM video clips. Embedded GPS coordinates automatically pin photos onto interactive OpenStreetMap or Mapbox views, allowing travel albums to display alongside synchronized GPX track routes. Powerful boolean search expressions filter across dates, keywords, camera models, and Adobe XMP face regions without requiring expensive background machine learning models. Built-in link sharing creates password-protected access links with custom expiration dates for friends and family. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
