I think you meant an image of a drive with no partitions:

Ie.
 mkfs /dev/sdb. Create a filesystem on the entire disk, there is no offset and 
no partitions (the entire disk is the filesystem, no mbr or gpt).

 mkfs /dev/sdb1.  Create a filesystem on the first partition, there is an 
offset even if it is the only partition.  You examine the mbr or gpt to 
determine the offset.

Or possibly you meant an image of a partition:

dd if=/dev/sdb1 of=image_file.  Create the image of a partition, no offset 
needed for loopback mount.
