Fair enough. :-) ‘image’ would be about the same as the file name in
terms of useful alt text.

Possibly—while I was hacking on it, I couldn’t quite pin down when it
had an effect and when it didn’t.

Well, there /is/ a way to do that already, it’s just verbose:

,----[ Org ]
| * Foo
| #+ATTR_HTML: alt="The elusive foo in its native habitat."
| [[file:foo.png]]
`----

,----[ HTML ]
| <div id="outline-container-1" class="outline-2">
| <h2 id="sec-1"><span class="section-number-2">1</span> Foo </h2>
| <div class="outline-text-2" id="text-1">
|
| <p><img src="foo.png" alt="The elusive foo in its native habitat." />
| </p></div>
| </div>
`----

I’d suggest using the description part of the link as the alt text,
but then there’d be no way to provide the actual link text (or image,
as the case may be), so that’s a non-starter.
