Yep you're right, there was a second parameter being passed specifying
image/png, when I copy this URL and remove the offending parameter it
works fine. I'm not too sure how to make the AGG/PNG24 imageformat the
only one with a PNG mimetype, I've tried setting the name of the AGG
output format to image/png but that didn't help. I've tried looking
through the mapserver reference forcing the output of a particular
format, but can't find anything on that either. Any pointers on where I
can look for more info?

Thanks,
Simon
