PicPeak: event-focused self-hosted photo galleries with guest uploads

PicPeak is an open-source (MIT), self-hosted photo and video gallery platform that treats each gallery as an event. Galleries can be password-protected, set to expire and shared by link, and visitors can download images or the whole collection as a ZIP without an account. Guests can contribute photos directly, and a live slideshow mode displays incoming photos during an event. Deploy with an all-in-one Docker image using SQLite, or a Docker Compose stack with PostgreSQL and Redis. Storage supports local disks and S3-compatible backends, and existing media directories can be referenced without copying.
