... if you know how to use 'mount': yes, there is a utility :)

First mount the partition where you have the iso.image.

then:
mount /some/path/to/some.iso /mountpoint/ -o loop=/dev/loop0

on /mountpoint/ you'll have the iso now which you can view as if it
were a CD with files on it ... :)

To unmount all this do these 3 commands (and never ever forget it :))
umount /dev/loop0
losetup -d /dev/loop0
umount /partition/from/step/one

It's a dangerous thing if you make a mistake and then cannot umount
your partitions ...

Please check my suggestions very carefully (Google etc. ...): if
I made a mistake you'll have a big problem ...

man losetup
man mount
