/*
Plugin Name: Photo-List
Description: Displays all images in a directory in list fashion
Author: Sebastien Benoit
Author URI: http://www.gwcphoto.ca/contact/
Version: 3.1.0
*/

/*  Long Description: This script can be used as a drop in replacement for Apache's Fancy Indexing, 
        or simply to display images/file list in a directory where the script exists.
        It does a good job of displaying EXIF/IPTC properties of a photo, while also pulling standard
        EXIF GPS coordinates to create a Google maps link to the capture location.
    Notes: You'll need a few icons to compliment this code, namely /icons/folderbw-16.png, /icons/filebw-12.png, 
        /icons/geotag-16.png and /icons/external-12.png (download them from this server if you like). 
        If you are using Apache, you can add them to the Apache2[.2]/icons/ folder so all sites 
        of your server have access to them.
