QR Image Upload Camera adds an upload-based QR input fallback for camera-only QR scanner pages.
When a scanner page opens the camera, the add-on can let the user choose an image containing a QR code, preview it, confirm it, and present it to the page as a temporary camera-like stream. This is useful when a QR code is available as an image or screenshot on the same device.
The add-on only runs on the configured target site. It also includes a feedback form and sends basic scan result diagnostics for monitoring, such as whether a scan request succeeded or failed and a sanitized reason. It does not intentionally send QR tokens, raw attendance payloads, latitude, longitude, or uploaded images.
