James,
If you're accessing mapcache through untiled WMS calls (which is
probably the case), then the format used by mapcache for returning
images is defined in the wms service block
(https://github.com/mapserver/mapcache/blob/branch-1-2/mapcache.xml.sample#L819
, https://github.com/mapserver/mapcache/blob/branch-1-2/mapcache.xml.sample#L855
). You can set it to jpeg if you are serving data with no
transparency, or png in your case.
