        We dynamically generate this, since we want it the expiration clock to
        start when the message is created, not when the record is created.

        Arguments:
            name (str): Name of the image (e.g. "photo_id" or "face")

        Keyword Arguments:
            override_receipt_id (str): If provided, use this receipt ID instead
                of the ID for this attempt.  This is useful for reverification
                where we need to construct a URL to a previously-submitted
                photo ID image.

        Returns:
            string: The expiring URL for the image.
