If you have either Netscape 6.2 + or Mozilla 1.0 + installed on your system
use either to visit the following:

Place your cursor over the larger image, right click and select Properties.
The Display Box will show the various properties of the image, including
whether or not there is a Description (this time, of course, there is...).
Click on that link to see the Longdesc file.

While it's a strange implementation, it *is* useful when showing the
uninitiated the *how* and *why* of longdesc, which is why I created the
above page.  Currently IBM HPR and the latest JAWS release support Longdesc
by announcing the presence of the link, not sure about other adaptive
technologies (pwWebspeak used to acknowledge the longdesc, but I could never
figure out how to actually access the file...).  See my spin on the "D Link"
as well... (same page).

Good Luck.
