I am also always using graphics, not images when I need to display
clickable or non-clickable irregularly shaped regions of larger images
(maps, species pictures, etc.) It is very convenient, indeed, and it is
easy to make them more responsive to user actions like for instance
changing colors of border or background on mouse enter, mouse click,
mouse leave, etc... Or even darkening color with each iteration of
displaying, so that the first polygons displayed become gradually
darker, and the last are always the most bright ones :-)
Best wishes

it is well known but often overlooked that when using a graphic
(transparent/noop) as an irregulary shaped 'hot spot' over an image that you
can put two or more irregulary shaped areas into one graphic. You can do
this by putting the points of the second graphic after the points of the
first graphic but you separate them by an empty line.
For example you have a map and you want to make the USA clickable but Alaska
and Hawaii are not part of the contiguous USA. In that case you could make
one graphic with the points of the continental USA appended by the points of
Alaska and the points of Hawaii. You would only need one graphic to take
care of the clicks to the USA.

Thanks everyone - lots of great suggestions. Think the noop graphic is the
way to go for this application.
NB I can get quite a nice rollover by using:
on mouseEnter
set the ink of me to "blendDarken"
end mouseEnter
on mouseLeave
set the ink of me to "noop"
end mouseLeave
in the behavior of the overlay graphic.
