Jeff suggested I send this question here . . . . Although I'm not positive at all whether the problem is with MS4W at all. 

Right now I'm trying to open a MapServerCGI image link from a MS4W Mapserver (downloaded MS4W yesterday) on a Thumb drive. 

I keep getting a image error to the effect: 

The image "<Mapserver URL here>" cannot be displayed, because it contains errors. 

The headers look correct from the CGI because I switched the imagetype from GIF to PNG just fine, but FF gives me that error a,d I only get a broken Icon from IE for the same link. . . . 

All the google result point at a SKYPE extention, but I don't have SKYPE even installed on this computer. 

Firebug says 200ok, but only the browser error shows.  Still investigating . . . 

Anyone run into something similar.?
