Well I got this back from the cod.edu site:
404 - File Not Found
Before you email us about a broken link, please use our website (weather.cod.edu) to navigate
to the area of the website in which the link should exist. Deep linking directly to a particular
image or file is always dangerous as we do not guaruntee that links will never change.
For an edu site, they can't spell check!! "Guaruntee" instead of the correct spelling "guarantee"!!!
I gave up on their satellite images when they switched formats and went with the ADDS service from NOAA and haven't looked back until now, they really hid all the good data that was easy to get to at first.
