Hi Mark,

You can treat this image as if it was a RASTER data source.  You will need 
to download the image locally and then create a world file for it.  I 
suspect the RASTER howto would be of assistance.

If you are looking for raw visible and infrared satellite data for the US, 
my page might be of assistance.
