# NAME:		Image Mounting Script
# AUTHOR:	Magnus Anderson <anderson@sonic2000.org>
# LICENSE:	GPL (http://www.gnu.org/licenses/gpl.html)
# REQUIRES:	cdemu, zenity, gnomesu
# VERSION:	1.1
# DESCRIPTION:	A script that will mount ISO, CUE and NRG files with ease.
#		It will use cdemu to mount cue/bin files.
#		Gnomesu is used to make sure users are able to mount images even tough we have no fstab entry
# CHANGELOG:	1.1: My system for checking for a valid extention for the file was not working as it should
