Adding Links
As a hypertext system, HTML allows you to link portions of a document to other locations that can be in either the same document or other documents. When a Web browser sees a link, it signals the available links to the user by underlining or coloring the link region. The link markup tag in HTML is <A> (denoting “anchor”). This is followed by the URL of the destination document. You can also include a link to your e-mail. This is done by using the URL tag, mailto and then your e-mail address. To add a link follow these steps:
Begin your anchor with “<A”. Don’t forget the space after the A.
Enter the URL of the destination document by typing HREF=“URL” (HREF stands for hyper reference.
Enter “>”.
Enter the text that serves as the name or pointer to the destination document.
Enter the closing container tag, </a>.

Adding Images
Including images in your Web document is very easy with the <IMG> (image) format tag. The two formats supported by HTML are GIF, CompuServe’s Graphics Interchange Format and JPEG, the industry-standard Joint Photographic Expert Group format. The HTML tag that you use to place a graphic image is the Image tag <IMG>. It is used along with the source attribute (SRC), which is a reference to the location of the image file. To place an image on a Web page follow these steps:
Type <IMG SRC=“filename.gif or .jpeg”
Type a closing angle bracket (>)
You can also modify the image on your web page. Below are tags and descriptions for adding images and modifying images to you Web page.
