A blind
user has few cues to tell what an image is about without <code>@alt</code>, and other users
may have no way of understanding what video or audio contents are about either.</p>

<p>(For images whose <code>alt</code> attributes would introduce redundancy, and for images
whose purpose is purely decorative which you cannot immediately use CSS for, use
no alternative text, as in <code>alt=""</code>.)</p>
