/*
  This script is a helper script for the 'Gallery Import' Facebook Application.
  @version r5

  Instructions:
    1. Create a new 'fb' subdirectory in your Gallery installation (using FTP or SSH), i.e. in the directory that contains main.php etc.
    2. Rename this file 'export_fb.php' and upload it in this new directory.
       The resulting script should be available at: http://your_gallery_url/fb/export_fb.php
       This URL is what the 'Gallery Import' Facebook Application will ask you in Step 1.
