If you don't provide an IMAGETYPE the first configured output format will
be used.  If you declare any in your mapfile, the first of those should
be used, otherwise it will be the first internal one.  Normally the first
internal one is either GIF or PNG.

I would encourage using an explicit IMAGETYPE to avoid hard-to-diagnose
problems when you upgrade and things change around a bit.  However, for
hacking up prototypes it isn't too important if you are happy with what
gets selected.
