Todot Photolab for WooCommerce

Photolab streamlines selling digital photos at scale through WooCommerce. Upload thousands of photos in batches, apply watermarks inline during upload, and publish each as a downloadable product — all from a single admin panel. Built for event photographers, photo studios, and anyone selling large galleries online.

Key features:

• Bulk chunked upload (5 files per chunk, supports 2000+ photos per album)

• Inline watermarking during upload — no background queue drift; Imagick preferred, GD fallback

• Configurable watermark position: full-width or bottom-right

• Each photo becomes a virtual downloadable WooCommerce product

• Original photos protected from public access; customers download only after purchase

• Download blocked until processing completes (HTTP 425 during watermarking, 410 if expired)

• Multi-upload: up to 3 concurrent album uploads per user with rate limiting

• Automatic recovery of interrupted uploads (client heartbeat + server-side cron, FSM with aborted state and manual reset)

• Idempotency-Key on chunk endpoints for safe retry after network timeouts

• Distributed lock (MySQL GET_LOCK / transient fallback) for multi-server deployments

• Daily cleanup failsafe: stuck photo detection, retry budget, orphan scan, log retention

• Structured logging with auto-context (user_id, album_id, photo_id) and sensitive data redaction

• Album expiration management with automatic cleanup

• SHA-256 deduplication to prevent duplicate photos in the same album

• SPA admin panel with zero page reloads, REST API communication

• Imagick support (recommended) with GD fallback for image processing

• WooCommerce HPOS compatible
