You can specify an offset to the loop back with mount -o loop,offset=32256
The offset seems to be the start you get from fdisk * 512

I found the info from:

Hi all i am a newbie to Unbuntu and i am really enjoying. I am
studying Linux operating systems as a part of a computer forensics
degree. Iam trying to get a better under standing of images/iso and i
have un into a road block one of the images i have has multiple
partions on it.

student at student-desktop:~/Desktop$ fdisk -l -u Image3.img
You must set cylinders.
You can do this from the extra functions menu.

Disk Image3.img: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x73696420

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order

from what i can tell the image is not from a linux system more of a
windows system how ever i would still like to know how to mount one of
more of the partions in the image.
