[Chameleon] Error Rendering Map Image

Fri Aug 19 01:40:55 EDT 2005

Hello-

I think I have narrowed it down. It seems to simply be a problem with the 
IMAGETYPE tag. The old versions of the applications were using PNG24. Once 
this was changed to PNG in each of the mapfiles, the applications worked as 
expected. Thanks again for your help.
