I want to right click on an iso file and have it mounted/unmounted automatically (actually, my users want this). It would be nice if the program allowed editing and remaking the iso but that is not necessary.
Linux Mint 17 comes with Disk Image Mounter, but if not:
sudo apt-get install gnome-disk-utility
Furius Iso Mount (might not have right click, but allows editing and remaking I think)
sudo apt-get install furiousisomount
Isomaster (might not have right click, but allows editing and remaking)
sudo apt-get install isomaster
