Alternatively, avoid table-based page layouts.

To clarify: the longdesc attribute contains the URL of a page that
provides a substantive description of the image.  Speaking browsers may
opt to read the alt or title attributes (or both).  IMO, longdesc isn't
necessary for icons, etc., whose meaning can be grasped from a brief
title.

Mozilla-based browsers, including Netscape 6.2, provide a link to the
longdesc page under the context menu's image properties.  I don't know of
any other browser that touches longdesc.
