## Nautilus
## SCRIPT: 09_multi-img-files_APPEND_horizORvert_convert-append.sh
##
## PURPOSE: Passes a selected set of selected image filenames ('.jpg' or
##          '.png' or '.gif' or whatever) to the ImageMagick 'convert'
##          command.
##
## METHOD:  Uses 'zenity --list --radiolist' to prompt for 'Horiz' or 'Vert'.
##
##          Uses the 'convert' command with either the '-append' (vertical)
##          or '+append' (horizontal) option.
##
##          Makes the output filename based on the name of the FIRST
##          selected input file.
##
##          Shows the new output (appended) file in an image viewer of
##          the user's choice.
##
## HOW TO USE: In Nautilus, select one or more image files in a directory.
##             Then right-click and choose this script to run (name above).
