I have a Sky Drive account I set up for the members of our Deep Space Imaging group with this very idea in mind. I put them all into .rar files with the flats and darks to be downloaded to do it all yourself or you can choose a calibrated image and just Photoshop it. These are full rez though. Do you want the link JJJ? I have heaps of spare storage if you need it.
Great idea for IIS though!
