FW: [Chameleon] CwcImage_0 when upgrading to Chameleon 2.6

[Jeff McKenna]

John,

I can speak regarding your ms4w issues: the chameleon package (on the 
MS4W downloads page: 
http://www.maptools.org/ms4w/index.phtml?page=downloads.html) needs *NO* 
configuring in order to work with MS4W 2.2.9.  If you are using that 
exact chameleon package and MS4W 2.2.9 and still getting those errors 
that would be really really odd.
