loop knows about an offset:

First find where your partitions are:

% sfdisk -l -uS hdc_img
Warning: hdc_img is not a block device
Disk hdc_img: cannot get size
Disk hdc_img: cannot get geometry

Disk hdc_img: 0 cylinders, 0 heads, 0 sectors/track

Units = sectors of 512 bytes, counting from 0

   Device Boot    Start       End   #sectors  Id  System
 hdc_img1            63    112454     112392  83  Linux
 hdc_img2        112455    401624     289170  82  Linux swap
 hdc_img3        401625  33736499   33334875   5  Extended
 ...

OK, let us mount this first one, at an offset of 63 sectors.

% bc
63*512
32256

# mount hdc_img /mnt -o loop,offset=32256
#
