PNG is Portable Network Graphic, one of the newer format newer graphic
formats supported by GD in lieu of GIF.   Yes, that would be the image
format generated by mapserver.  For further info, see http://www.boutell.com/gd
Unisys holds the patent for GIF LZW compression...
PNG is supported by the newer versions of MS Internet Explorer and 
NetScape Communicator and is legally unemcumbered..

To the best of my knowledge output of GIF or PNG is mutually excusive depending 
on the version of GD that you are compiling into mapserver.  Note that some of 
the old web browsers will not display PNG images.  Yes you can use PNG for
reference map and symbols/markers, but this will take a bit of work on your
part.
