ImageMagick Wallet Maker

I've got an older script for making thumbnails and contact sheets from a folder of images.

Recently Phillip Vuchetich sent me a related script for taking images, scaling them to wallet sizes and composing them onto 4x6 sheets for easy printing from kiosks. It's a neat application of the idea, and he said I could post his script, so here it is. It's also part of my helper-scripts repo at Github.

Thanks Phillip!

# Wallet Photo Script using ImageMagick
#
# Copyright (c) 2012 Phillip Vuchetich
#
# Permissions for the Wallet Photo Script are the same as the original script by John Hobbs.
#
# This script was created to take an entire directory of photos as input,
# rotate them to portrait layout, and create composite 2x2 sheets, suitable
# for printing wallet sized photos standard 4"x6" (US) photo paper.
# This was created to make it easy to send photos suitable for wallets or
# scrapbooking sized photos to retail photo printing locations.
# The use case is a manually pre-selected copy of images that are all placed
# in the input directory (the current directory).
# An output directory will be created if it does not exist.

# Original script from John Hobbs:
# Digital camera thumbnail/contact sheet tool.

### SETTINGS ###
# Scaling Methods:
# resize (Best/Slow)
# scale (Middle/Middle)
# sample (Worst/Fast)
METHOD="resize"

# Wallet image Size
# For Wallets intended for 4" x 6" output, should be a multiple of 4x6 to minimize cropping.
# Example: for 4x6, 300ppi use 600x900 (for each photo to be 2"x3").
# For 400 ppi use 800x1200
# Talk to your photo print shop to ask what resolution the printers use, so that their image
# software does not need to resize your image, as resizing will likely reduce quality a little.
# Expect to see some white space, depending on the original image dimensions.
# No cropping is performed.
