Jacob, the problem is that i DO need transparency (in IE) with 24Bit output.

As demonstrated here: http://thickskin.dyndns.org/kamap/ if you select the
map with an 8 bit PNG, the color quality of my pretty picutres deteriorates.


There is solution at http://koivi.com/ie-png-transparency/  but i need to
delve into the code a bit more.
i welcome any other suggestions?
