[mapserver-users] browse mode no longer saves images?

[geographika]

Thanks Steve. I persevered knowing it was still a valid use case.
Turns out it was a simple error / misunderstanding on my part. I've had 
the MAP STATUS set to OFF for years, and always accessed layers using 
WMS/WFS/GeoJSON.
It seems in CGI mode this means no map image is ever created (even when 
specifying layers to show). The map did appear in mode=map however, just 
not mode=browse.
