What does this mean?
<img> element inside a link must not specify alternative text that duplicates the
content of a text link inside or beside it.
For example, this code should be avoided:
<a href="/apple"> <img src="apple.png" alt="Apple"> Apple </a>
Accessible technologies will tend to see this as "Apple Apple". The correct behaviour is to
specify either a null (empty)
<a href="/apple"> <img src="apple.png" alt=""> Apple </a>
or to hide the image via
<a href="/apple"> <img src="apple.png" aria-hidden="true"> Apple </a>
