CIS89A - 4. Images and Media

A picture is worth a thousand words

It is easy and inexpensive to add pictures to web pages. This has been one of the most important changes that web publishing has made. Printing pictures on paper, especially in color remains very expensive. The additional data to include high resolution images to a web page is relatively little. So use images to tell your story and add interest to your web page.

    NOTE: Throughout the course there are a number of discussion activities that require research and comments. These are important because they address topics that web developers need to know about.
