Diagnoses
Here is how rule engines diagnose the image not named
issue for HTML element 691 of the Clean Air Task Force (CATF) page.
- <p>When screen readers encounter an image with no alt attribute at all, they dictate the url of the image file instead, often one letter at a time.</p> <p><strong>To fix:</strong> either add an empty alt (alt="") to indicate this image should be ignored by screen readers, or add descriptive alt text.</p> <p>Note that a <a href="https://www.w3.org/WAI/tutorials/images/informative" target="_blank" title="Opens in new tab">good alt describes the image's message</a>, not simply what it contains. Depending on the context, the alt for the picture of a child kicking a ball might emphasize the setting, the child, the kick or the ball:</p> <ul> <li>The sunny spring day brought kids to the park for some soccer.</li> <li>A.J. wearing the new team uniform.</li> <li>The game-winning kick curved in from the left sideline!</li> <li>The size 4 ball is the right size for this 9-year-old child.</li> </ul>
