## Nautilus
## SCRIPT: 09_multiAPPEND_imgFiles_horizORvert.sh
##
## PURPOSE: Passes a selected set of selected image filenames ('.jpg' or
##          '.png' or '.gif' or whatever) to the ImageMagick 'convert'
##          command.
##
##          Uses either the '-append' (vertical) or '+append' (horizontal)
##          parameter, as specified by the user (via a 'zenity' prompt).
##
##          Makes the output filename based on the name of the FIRST
##          selected input file.
##
##          Shows the new output (appended) file in an image viewer that the
##          user can specify.
##
## HOW TO USE: Select a bunch of image files in a directory, in Nautilus,
##             and then simply right-click this Nautilus script (name above)
##             to run.
