2.7. Images

We’ve shown how to mark up documents that contain only text, but web pages may also contain images, animations, graphics, audios and even videos. The most popular image formats used by web developers today are PNG (Portable Network Graphics) and JPEG (Joint Photographic Experts Group). Users can create images using specialized software, such as Adobe Photoshop Express (www.photoshop.com), G.I.M.P. (www.gimp.org), Inkscape (www.inkscape.org) and many more. Images may also be acquired from various websites, many of which offer royalty-free images (Fig. 2.5)—read each site’s Terms of Service to determine if you’ll need permission to use their images, especially in commercial, for-profit applications. Figure 2.6 demonstrates how to include images in web pages.
