 The following request sent by OpenLayers :
 http://vmap0.tiles.osgeo.org/wms/vmap0?LAYERS=basic&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A4326&BBOX=-135,0,-90,45&WIDTH=256&HEIGHT=256

 gets the response "loadOutputFormat(): General error message. OUTPUTFORMAT
 clause references driver GD/JPEG, but this driver isn't configured."

 This seems to have started last week sometime. It doesn't seem to be
 anything in my code, because it is occurring in older versions of our
 website that didn't have the issue.

 The following, which is the  recommended by OpenLayers also causes the
 same error message:
 http://vmap0.tiles.osgeo.org/wms/vmap0?LAYERS=basic&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&SRS=EPSG%3A4326&BBOX=45,-90,90,-45&WIDTH=256&HEIGHT=256

 on the Discuss Mailing list Steven Woodbridge notes as follows:
 "OK, interestingly that url works fine for me! But if I SHIFT-refresh a
 bunch of times I can get that error. So it seems that the load balancer is
 hitting one/some? server that is miss configured."

 "Also if you change the url to request image%2fpng it will still generate
 the error because the mapfile has defined in it and OUTPUTFORMAT with
 GD/JPEG defined but the version of mapserver installed on the server is
 NOT built with GD/JPEG support.

 The mapfile needs to be updated or a new version of mapserver needs to be
 installed with GD/JPEG support add to the ./configure command when it is
 built. "
