I recently installed AGS 10.1 on a customer site and noticed that by default the supportedImageReturnTypes value is being set to MIME. I can use the arcgis/admin console to update this to be URL, but I would have to do this for each map service.
The copy we have installed for development on our local server is set to URL by default.
I assume there is a default value setting somewhere, but I'm having trouble finding it and I'm uncertain why this default value would be different between servers when I'm fairly certain I never modified it.
Thanks,
