ABSTRACT
This chapter introduces the HyperText Markup Language (HTML) elements used to add images, as well as design principles that guide effective use of images in Web design. An image can be added to a Web page in two main ways. It can be embedded in the current page, or a link that points to its location can be provided. In the latter case, the image is usually displayed in a page by itself. Irrespective of whether an image is embedded or linked to, it can be used as an image map. Image mapping has many applications. It is especially useful for providing information about different areas represented on a geographical map that would be impractical to put on the map. Essentially, an image map enables geometric areas placed on an image to be associated with hyperlinks. Image resolution describes how many pixels an image has, and it is specified in two ways, namely pixel dimensions and megapixels.
