When dealing with a image with partitions, you need to use kpartx

# kpartx -a disk.img

Then look in 

/dev/mapper

You should see files like

brw-rw---- 1 root disk 253,  0 2008-06-04 15:43 loop0p1

representing the partitions in the image.

To mount them

# mount -t vfat /dev/mapper/loop0p1 /mnt/image

To clean up

# umount /mnt/image
# kaprtx -d disk.img
