[maplab-users] Preview isn't working after refresh in Mapedit.

[Zak James]

It looks like mapserver is not finding the temporary map file saved 
when you make a preview. The most common reason for this is that the 
Image Path and Image URL parameters in the web object of your map do 
not point to the same location.

If your web server's root is /var/www/html/, then the image path could 
be /var/www/html/tmp/ and the image url would then be /tmp/. The image 
path has to be a web accessible directory.
