[Mapserver-users] PHP/MapScript question: mapObj->processquerytemplate()

Steven,

It is quite possible that processQueryTemplate() doesn't generate the
images.  The processTemplate() function includes a boolean
'generateimages' flag to request the images to be created, but this flag
is not present in processQueryTemplate().  Perhaps you should file this
in bugzilla.
