Hi Joel, 
  You need to work out where in the disk image the partition starts:

  sfdisk -l -uS image_file.dd
  The offset is given in sectors (512 bytes), so multiply that by 512
  and you have the offset in bytes.

  mount -oloop,offset=xxxx image.dd /mnt/point

  This will work if the offset is less than 2G, other wise you can look
  for the NASA loopback driver which supports large offsets.
