ChapterÂ 7.Â Adding Graphics
Itâs safe to say that the creators of the Internet never imagined it would look the way it does todayâthick with pictures, ads, and animated graphics. They designed a meeting place for leading academic minds; we ended up with something closer to a Sri Lankan bazaar. But no oneâs complaining, because the Web would be an awfully drab place without graphics.
In this chapter, youâll master the art of Web images. Youâll learn how to add graphics to a Web page and to position them perfectly. Youâll also consider what it takes to prepare pictures for the Webâor to find good alternatives online.
To understand how images work on the Web, you need to know two things:
They donât reside in your XHTML files. Instead, you store each one as a separate file.
To display pictures on a page, you use the <img> element in your XHTML document.
Youâll use images throughout your site, even in spots where you might think ordinary text would work just fine (see FigureÂ 7-1).
If you canât tell whether a piece of content on a page is a graphic, try right-clicking it. If itâs an image, browsers like Internet Explorer and Firefox give you a Save Picture As option in a pop-up menu.
