I presume this happens only when the image is a link, that is, inside an <a
href> element. But does it happen when the <a href> element contains both
the image and some text?

In any case, it seems that the problem of reading images with alt="" can be
avoided by not making images links when there is a corresponding textual
link too.  After all, the only thing that such duplication serves is to
reinforce some people's tendency to click on anything to see whether it's a
link somewhere.

For image links without such duplication, the problem does not arise, since
the alt text can and should be descriptive of the meaning.
