## Nautilus
## SCRIPT: tile01b_1imgfile_MIRRORvert_convert-clone-flip-append.sh
##
## PURPOSE: Make a larger image file from a selected image file
##          ('.jpg' or '.png' or '.gif' or whatever) by adding a mirror-image
##          of the file --- in a north-south direction (vertically).
##
##          This is helpful in making 'tileable' files from non-tileable files.
##
## METHOD:  There is no prompt for a parameter.
##
##          Uses ImageMagick 'convert', with '+clone', '-flip',
##          and '-append'.
##
##          Shows the new image file in an image viewer of the user's choice.
##
## HOW TO USE: In Nautilus, select an image file.
##             Then right-click and choose this script to run (name above).
