        You presently have:
        
<A HREF="http://www.slcc.edu/cgi-bin/imagemap/map/new_button_bar.map";>
<IMG ALT="" BORDER=0 ALIGN=middle
SRC="/map/new_button_bar3.gif" ISMAP usemap="#new_button_bar3"></A>


If have not configured NO_ISMAP_IF_USEMAP to TRUE, nor toggled it TRUE
via the -ismap command line switch, v2.7.1+fotemods will use two
pseudo-ALTs, joined by a dash to indicate that they are variants of
a resource:

        [ISMAP]-[USEMAP]

If you replace the ALT="" with a "Lynx-friendly string", Lynx will use that
in place of the "[USEMAP]" pseudo-ALT, and depending on whether you have
set NO_ISMAP_IF_USEMAP to FALSE or TRUE, Lynx will offer either:

        [ISMAP]-Lynx-friendly string

or just:

        Lynx-friendly string
        
respectively,  I just downloaded your index2.html, and confirmed the above
behavior with it.

        ALT="" will block use of a psuedo-ALT in most cases, but not
for a USEMAP, because those are fully functional for Lynx, and not
likely to be just "decorative".
