I burned a couple of cds only to remember that I did not get the md5sum from the ftp server. I ran md5sum anyway and yanked the output with the mouse and then "middle clicked" that onto firefox, to give this value to google. http://md5sum.com was the first page to come up. May I suggest that all images old, current and forthcoming are listed to this site? Not sure how to contact those chaps. Google brings limited results, all pointng back to md5sum. This probably implies that it's a new site.
