Enter a file key (path) from your B2 bucket. The app will generate a secure, time-limited URL for it.
This is the path inside your B2 bucket, not a full URL.
1. Your media files live in Backblaze B2 (private bucket).
2. Store file keys (paths) in your Gallery entity, e.g. "clients/wedding-001/photo.jpg"
3. When a client opens a gallery, the app calls b2Authorize to get a download token.
4. File keys are replaced with secure, time-limited URLs (24h default).
5. Images render normally — existing full URLs pass through unchanged.
