1. Search for a site that uses image links to provide navigation. List the URL of the page.
What colors are used on the image links? If the image links contain text, is there good
contrast between the background color and letters on the image links? Would the page
be accessible to a visitor who is sight-challenged? How have accessibility issues been
addressed? Is the alt attribute used to describe the image link? Is there a row of text
links in the footer section of the page? Answer these questions and discuss your
findings.
2. When configuring an image map, describe the relationship between the image, map,
and area tags.
