Why? Regarding image maps, there are really just two useful rules:
1. Don't use them.
2. If you really have something that is _better_ presented as a clickable
image than as a list of links, make the clickable image an _alternative_
to the list of links. (For example, for selecting an area within a
country, first set up a list of links. Then, if desired, _add_ an
alternative, namely a clickable map.)

In case 2, you should use alt attributes as a matter of principle, but
they aren't really needed when you have the list.

Then they are simply wrong. Try any graphic browser with image loading (or
just display) switched off, and you'll see. More info:

That's one problem, and potentially relevant to (literally) billions of
people, but the main problem is in getting the alt text appear in the
first place.

Well, what's the URL? There might be an error in your document.
