How to Fix the Problem

The <img> element that is located inside an <a> (i.e. link) element should use an alternative text (alt attribute) which supplements the link text and describes the image. Otherwise it should use a null value. Example: <a href="home.html"> <img src="house.gif" alt="home page icon"> Go to the home page </a>

The Algorithm, in Simple Terms

Engine scans the page for any <a> element that contains an <img> element, and compares the “alt” attribute with the <a> inner text

Why Is it Important?

This helps users understand the purpose of each link so they can decide whether they want to follow the link.

Code Example

<a href="linknew.html">
<img src="/example_"skip.gif" alt="example_">
New link
</a>
