If you use Nautilus you can get all sorts of scripts to work with your
filesystem. This is a quick and dirty method to mount ISO's, once the
script is copied to the right location correctly all you have to do is
right click an ISO file and then click mount, or unmount if already
mounted. Then you will get an icon on your desktop. This is good for
Gnome users!
