Re: One more thought about requiring the alt to add to the pile

Hi David, at least it works as desired in Firefox.

I am going to contact Freedom Scientific about this difference in
behaviuor and see if they can't get "All graphics" mode to identify
graphics with null alt in IE, as it does in Firefox.

The idea of the alt="" is a flag that
AT can ignore the image, not that they must or are compelled to. under
default browsing it is appropriate that <img alt=""> is ignored as is
<img> (for most AT), but there is obvious utility in a mode that
identifies all images regardless of alt presence.
