Some people who browse Web pages turn off the display of movies and graphics so that they can browse the Web (World Wide Web (WWW): The multimedia branch of the Internet that presents not only text, but also graphics, sound, and video. On the Web, users can easily jump from item to item, page to page, or site to site by using hyperlinks.) more quickly.
You can specify alternate text (alternative text: Used by Web browsers to display text during image downloads for users who have graphics turned off and for users who rely on screen-reading software to convert graphics on the screen to spoken words.) to appear instead of graphics. You can specify text and an image to appear for a movie. In some browsers (browser: Software that interprets HTML files, formats them into Web pages, and displays them. A Web browser, such as Microsoft Internet Explorer, can follow hyperlinks, transfer files, and play sound or video files that are embedded in Web pages.), if the display of images and movies is turned on, alternate text might appear as the movie or graphic is downloading.
