[Mapserver-users] Bad PNG

[Bjoern Platzen]

Hmmm...

I'm not sure, but I think that IE has some problems with interpreting 
PNGs correctly.

In this case, I'd like to blame it on IE. (Though I don't think it's the 
whole truth...)
Maybe some of the 'MapServer-Gurus' have an idea...

Sorry, that didn't help you much...

Bye,

Bjoern.
