MS 3.7 handles output images differently than previous versions.  In 
your mapfile you can declare several output format types with the 
OUTPUTFORMAT object, then use IMAGETYPE to identify the output format 
you want to use.  saveImage() and saveWebImage() look at the parameters 
declared in whichever outputformat is in use, and use those parameters 
to create the output image.  So, instead of using something like 
$img->saveImage($img_name,'MS_PNG',0,0,0); you can just use 
$img->saveImage();.

See http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?OutputFormat for 
detailed information about the OUTPUTFORMAT object.  See 
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?MigrationGuide for changes 
that you need to make when migrating to 3.7.
