// @Johan: Misschien een goed idee om dit ook in een apart php scriptje te zetten, voor de overzichtelijkheid.
// En om deze reden (Citaat uit de piwigo docs http://piwigo.org/doc/doku.php?id=en:plugins):
// Code size
// When PWG loads the plugins, it will include every main.inc.php.
// Don't put in your main.inc.php 3000 lines of code just to add a page on the administration menu.
// Split you main.inc.php in several files and feel free to add include_once inside functions defined in main.inc.php as much as you want.
