#37 Help message incomplete

gpixpod --help ==> Usage: gpixpod.py [options]
etc.

but it would be better to say Usage: gpixpod.py [options] image[s] (or something) to make it clear that gpixpod requires image filenames (or directory names with the -r option?)
cf cp --help ==> Usage: cp [OPTION]... [-T] SOURCE DEST
etc
