The problem had nothing to do with the use of the loop
device.  The "mount" commands were the problem.  They
needed the "-o umask=0" option, so that Samba's "nobody"
user could access the mounted partitions:

   mount -t ntfs -o umask=0 /dev/loop1 /mnt/img1
   mount -t vfat -o umask=0 /dev/loop2 /mnt/img2
