Transparent gif's are invisible whether images are turned on or off,
hence the name transparent. The reason for having a transparent
gif for each link in the image map (as well as the image map) would
be so that alt text would display for each link when images are
turned off in the browsers. When images are turned off in a
browser, alt text for the individual hotspots (that is, alt text for each
<area> tag does NOT show - in IE and I imagine in other browsers
also, although I haven't had a chance to test the others). For alt
text for a transparent gif, the alt text would display with images off.

No, this is not the case in IE. With images turned off, the individual
alt text for each <area> element does not show - only the alt text
for the imagemap image does. Hence, my initial email.

With images off in IE5, the alt text for your <area> elements in
your imagemap do not display.

Warmest regards to all also, in these very difficult times.
