Aha, the Southern Hemisphere folks come alive... <grin/>

Anyway, yes, I try to have both d-links and longdesc, and I ignore warnings
from computers that are not as smart as people.. As to the text for a d link
this is always difficult. One reason I tend to use the same link title is
that it can be difficult to identify the image in question - unless it has a
title, or it made sense that it was very clearly identified in the alt as an
image, there may not be much clue unless people are specifically checking
for images.

As Kynn pointed out, it would be better to have a way of annotating images or
transcoding pages so that it is not necessary to have the little "d"
everywhere. In fact such a thing is provided by the W3C Annotea system (I
think I mentioned it last week and wanted to produce an example), which
allows a description of an image to be associated with the image itself. At
the moment this works in Amaya, or in any browser that supports javascript,
or via a Web interface that is unfortunately not really really user friendly,
but I have some thoughts  about how to make it work a little more easily -
I'll take them up with the Annotea crowd.
