Mount a iso file
sudo mount -o loop -t iso9660 filename.iso /mountpoint
sudo umount iso/
[edit]A easy way
download two shell file, and add them to right click.
Using Nautilus Scripts
I am taking this tip from here first you need to download two scripts for mount iso images download from here for unmount iso images download from here
Once you have these two scripts you need to change the permissions using the following commands
sudo chmod +x /home/username/mount.sh sudo chmod +x /home/username/unmount.sh Now you need to copy them nautilus scripts sudo mv /home/username/mount.sh ~/.gnome2/nautilus-scripts/ sudo mv /home/username/unmount.sh ~/.gnome2/nautilus-scripts/
