Этот контейнер, я так понял отвечает за скрипт слайдера.

/**
* Add javascript files for front-page jquery slideshow.
*/
if (drupal_is_front_page()) {
drupal_add_js(drupal_get_path('theme', 'business') . '/js/sliding_effect.js');
}
Подскажите плиз.
Вот код всего файла.
jQuery(document).ready(function($) {

//Set Default State of each portfolio piece
$(".paging").show();
$(".paging a:first").addClass("active");

//Get size of images, how many there are, then determin the size of the image reel.
var imageWidth = $(".window").width();
var imageSum = $(".image_reel img").size();
var imageReelWidth = imageWidth * imageSum;

//Adjust the image reel to its new size
$(".image_reel").css({'width' : imageReelWidth});

//Paging + Slider Function
rotate = function(){
var triggerID = $active.attr("rel") - 1; //Get number of times to slide
var image_reelPosition = triggerID * imageWidth; //Determines the distance the image reel needs to slide

$(".paging a").removeClass('active'); //Remove all active class
$active.addClass('active'); //Add active class (the $active is declared in the rotateSwitch function)

$(".desc").stop(true,true).slideUp('slow');

$(".desc").eq( $('.paging a.active').attr("rel") - 1 ).slideDown("slow");

//Slider Animation
$(".image_reel").animate({
left: -image_reelPosition
}, 500 );

};

//Rotation + Timing Event
rotateSwitch = function(){
$(".desc").eq( $('.paging a.active').attr("rel") - 1 ).slideDown("slow");
play = setInterval(function(){ //Set timer - this will repeat itself every 3 seconds
$active = $('.paging a.active').next();
if ( $active.length === 0) { //If paging reaches the end...
$active = $('.paging a:first'); //go back to first
}
rotate(); //Trigger the paging and slider function
}, 10000); //Timer speed in milliseconds (3 seconds)

};

rotateSwitch(); //Run function on launch

//On Click
$(".paging a").click(function() {
$active = $(this); //Activate the clicked paging
//Reset Timer
clearInterval(play); //Stop the rotation
rotate(); //Trigger rotation immediately
rotateSwitch(); // Resume rotation
return false; //Prevent browser jump to link anchor
});

});
В таком коде я не силен.
