It takes one argument, which is this Image instance. It should use get_payload() and set_payload() to change the payload to the encoded form. It should also add any Content-Transfer-Encoding or other headers to the message as necessary. The default encoding is Base64. Any additional keyword arguments are passed to the base class constructor, which turns them into parameters on the Content-Type header.
