 * Thickbox 2.1 - One Box To Rule Them All.
 * By Cody Lindley (http://www.codylindley.com)
 * Copyright (c) 2006 cody lindley

 *http://www.opensource.org/licenses/mit-license.php
 * Thickbox is built on top of the very light weight jQuery library.
 * Modified for SPIP <www.spip.net> by Fil <fil@rezo.net>:
 * Modified by BoOz@rezo.net
 * - added recognition of images based on a.type
 * - added an image gallery
 * - added keyboard navigation ('n'ext (->), 'p'revious (<-), 'q'uit (esc))
 * - customize path to the css and wheel image
 * - default size for thickbox links that have no width x height indicated ??
 * - don't load css when not needed ??
 * - TODO: don't load js when not needed!!
 
 * Adaptations par Jean-Yves Giraud pour SPIP (http://jygiraud.free.fr/) (10/06/2009) :
 * =====================================================================
 * - Francisation des zones … cliquer (<- Précédente ; Suivante -> ; Diaporama ; Stop) et des bulles d'aide
 * - Correction de l'arrêt du mode Diaporama : on réaffiche l'image actuelle en remplaçant la zone [Stop] par [Diaporama]
 * - En mode diaporama, les touches <- et -> sont désactivées (les zones à cliquer également)  
 * - Ajout des zones à cliquer [+ rapide] et [- rapide] pour contrôler la vitesse du diaporama (4 secondes par défaut)
 *   Le délai est réinitialisé à 4 secondes à chaque lancement du mode diaporama 
 * - Seules les touches ESC pour sortir, et les touches <- et -> pour image précédente et image suivante sont conservées
 * - Homogénéisation des syntaxes (pour une meilleure lecture)
 * - Ajout de commentaires
 * - En mode Diaporama, le clic sur l'image (pour image suivante) est désactivé
