Some think that images in HTML-formatted E-mail messages are somehow embedded within the source of the message, that they are in-line. Instead, images are generally binary files that traverse the Internet as distinct packets not embedded in the source. At least that's how HTML-formatted messages reach my ISP's mail server. -- David E.
