  3:  * An adaption of the jQuery Cycle2 script: http://jquery.malsup.com/cycle2/
  4:  *
  5:  * Shows slideshows of images of an album. Slideshows are responsive by default but beware of theme css.
  6:  *
  7:  * Slideshow
  8:  * The theme file <var>slideshow.php</var> is required witin your theme's folder. A <var>slideshow.css</var> is optional.
  9:  * Required special css should best be incorporated into the theme's css.
 10:  *
 11:  * If you are creating a custom theme, copy these files from an official Zenphoto theme.
 12:  * Note that the Colorbox mode does not require these files as it is called on your theme's image.php and album.php directly
 13:  * via the slideshow button. The Colorbox plugin must be enabled and setup for these pages.
 14:  *
 15:  * <b>NOTE:</b> The jQuery Cycle and the jQuery Colorbox modes do not support movie and audio files.
 16:  * In Colorbox mode there will be no slideshow button on the image page if that current image is a movie/audio file.
 17:  *
 18:  * You can also place the <var>printSlideShow()</var> function anywhere else on your theme to call a slideshow directly.
 19:  *
 20:  * Content macro support:
 21:  * Use [SLIDESHOW <albumname> <true/false for control] for showing a slideshow within image/album descriptions or Zenpage article and page contents.
 22:  * The slideshow size options must fit the space
 23:  * Notes:
 24:  * <ul>
 25:  *  <li>The slideshow scripts must be enabled for the pages you wish to use it on.</li>
 26:  *  <li>Use only one slideshow per page to avoid CSS conflicts.</li>
 27:  *  <li>Also your theme might require extra CSS for this usage, especially the controls.</li>
 28:  *  <li>This only creates a slideshow in jQuery mode, no matter how the mode is set.</li>
 29:  * </ul>

660:      * a) Use on your theme's slideshow.php page and called via printSlideShowLink():
661:      * If called from image.php it starts with that image, called from album.php it starts with the first image (jQuery only)
662:      * To be used on slideshow.php only and called from album.php or image.php.
663:      *
664:      * b) Calling directly via printSlideShow() function (jQuery mode)
665:      * Place the printSlideShow() function where you want the slideshow to appear and set create an album object for $albumobj and if needed an image object for $imageobj.
666:      * The controls are disabled automatically.
667:      *
668:      * NOTE: The jQuery mode does not support movie and audio files anymore. If you need to show them please use the Flash mode.
669:      * Also note that this function is not used for the Colorbox mode!
670:      *
671:      * @param bool $heading set to true (default) to emit the slideshow breadcrumbs in flash mode
672:      * @param bool $speedctl controls whether an option box for controlling transition speed is displayed
673:      * @param obj $albumobj The object of the album to show the slideshow of. If set this overrides the POST data of the printSlideShowLink()
674:      * @param obj $imageobj The object of the image to start the slideshow with. If set this overrides the POST data of the printSlideShowLink(). If not set the slideshow starts with the first image of the album.
675:      * @param int $width The width of the images (jQuery mode). If set this overrides the size the slideshow_width plugin option that otherwise is used.
676:      * @param int $height The heigth of the images (jQuery mode). If set this overrides the size the slideshow_height plugin option that otherwise is used.
677:      * @param bool $crop Set to true if you want images cropped width x height (jQuery mode only)
678:      * @param bool $shuffle Set to true if you want random (shuffled) order
679:      * @param bool $linkslides Set to true if you want the slides to be linked to their image pages (jQuery mode only)
680:      * @param bool $controls Set to true (default) if you want the slideshow controls to be shown (might require theme CSS changes if calling outside the slideshow.php page) (jQuery mode only)
