John,

Put the:

   IMAGETYPE JPEG

keyword in your MAP section.  The OUTPUTFORMAT declaration you provided
has no effect unless you select the format, but for web purposes you likely
don't want to be returning geotiffs, so just select JPEG or PNG24 - the two
common 24bit image formats for the web.

Best regards,
