Abstract:

Perhaps the most powerful aspect of computing technology is the ability to combine text, graphics, sounds, and moving images in meaningful ways. The promise of multimedia has been slow to reach the Web because of bandwidth limitations, but each day brings new solutions. Although there are numerous methods for creating Web multimedia, we recommend using stable technology that works for the great majority of client machines. Plug-ins that extend the capabilities of your Web pages are a mixed blessing. You risk losing your audience if you require them to jump through hoops to view your content.
