[ka-Map-users] Help, I can't figure this out

[Stephen Woodbridge]

The problem is that the two images are from the SAME mapfile!

OK, I see the problem. the config.dist.php you now have a bunch of image 
format stuff. I have been using PNG8 as defined below and not PNG24, but 
they is no PNG8 block in the case statement. Do I need to add something 
for PNG8 or is the PNG24 configured the same way as my PNG8?
