#                         the default is vertical
# -image <imagefilename>
#                         Specifies an image to be used in the volume button
#                         The image must be a gif image.
# Both parameters are optional. You can use shorhand for the parameters -o -i
# e.g.
#  mini-volume -o hor -i /root/myimage.gif
