To mount an ISO image on hard disk so that it can be read, try this:

   # mount -r -o loop /path/to/iso/image.iso /mount/point

"/mount/point" can be any empty directory.  I create "/mnt/tmp" and
keep it handy for just this purpose.

You cannot modify an ISO image on the fly.  The Linux kernel knows how
to read ISOs, not how to create them.  For that, you use the
command-line utility "mkisofs".  This utility is also what's used
under the covers when you use one of the GUI tools.

The ISO file structure was never designed to be modified, but there is
an alternative:  UDF.  This is the file system used for DVD disks.
Newer Linux kernels have a UDF driver, but I have not worked with it.
