If you want to mount/unmount your ISO image by directly right-clicking on it, you can do this from your home dir:

% gedit Mount


Copy this script into Mount file
#!/bin/bash
#
for I in "$*"
do
foo=`gksudo -u root -k -m "Enter your password for root terminal access" /bin/echo "got r00t?"`
sudo mkdir /media/"$I"
sudo mount -o loop -t iso9660 "$I" /media/"$I" && nautilus /media/"$I" --no-desktop
done
done
exit0


Save and close, than do the same with unmount file:
# gedit Unmount


Copy these script into Unmount file
#!/bin/bash
#
for I in "$*"
do
foo=`gksudo -u root -k -m "Enter your password for root terminal access" /bin/echo "got r00t?"`
sudo umount "$I" && zenity --info --text "Successfully unmounted /media/$I/" && sudo rmdir "/media/$I/"
done
done
exit0


Make them executable with:
% chmod +x Mount
% chmod +x Unmount
