A key component of a compelling Web site is the use of
interesting and appropriate graphics. This chapter introduces you to working
with visual elements on Web pages.
When you include images on your Web site, it is important to remember that
not all Web users are able to view them. Some users may have vision problems
and need assistive technology such as a screen reader application that reads the
Web page to them. In addition, search engines send out spiders and robots to
walk the Web and catalog pages for their indexes and databases; such pro-
grams do not access your images. As a Web developer, you should create pages
that are enhanced by graphical elements but that are usable without them.
