I made an ISO this way: sudo partimage save /dev/sdc1 /media/56AE8240AE82191F/Backup/xfcefat.iso
The resulting iso file is very small but when mounted I see that it has correctly preserved the partition information.
The problem is my partition was 8gigs and only had like 100mb of data on it.
I want to fix the partition information on the iso and tell it to think it is only a 500mb partition.
How can I shrink it's partition information?
If it was a usb drive I could do this with gparted and shrink it just fine. But this is an iso file raw copy clone of my disk.

You could simply re-create the image "from scratch" with
mkisofs
.If you don't have the CD-ROM available anymore, loop-mount the iso image with:
(And don't forget to unmount it.)
This will not copy boot information from the DVD. If you need that, a little more work is necessary to extract to boot information and pass it as an option to
mkisofs
.
