#photobooth.sh is a script to automate image processing and printing for unattended photobooths.  It was originally designed to work with Cheese webcam software, though the original source of images isn't important.  Any JPEGs dropped in $PHOTODIRECTORY will be combined into a filmstrip and are formatted to be printed on 4x6 or 5x7 paper.
