Salve, una domanda da ignorante in materia.
Ho applicato a una parte del mio sito uno script preso da qui per lo slide show
(è quello che vedete in home : http://freankexpo.net )

Le immagini come vedete passano da una all'altra tramite dissolvenza.
Questo effetto di dissolvenza è per caso regolato da questo script?

codice:
(function($){
    $.fn.cleanSlider = function(config){
        var sliders=$(this);
        sliders.addClass('clean_slider_container');
        sliders.css('width',config.width);
        sliders.css('height',config.height + 20);


        var changeEffects = function (elementToHide,elementToShow){


            if (!$(elementToHide).size())
                {
                    elementToShow.addClass('clean_slider_image_shown');
                    elementToShow.fadeIn('fast');
                }else{

                    elementToHide.fadeOut('fast',function(){
                        elementToHide.addClass('clean_slider_image_shown');
                        elementToShow.fadeIn('slow');
                        elementToShow.addClass('clean_slider_image_shown');
                    });
                }
        }
        var showImage = function (slider,imageNumber){
            var prevImageNumber = $(slider).attr('data-image');
            var elementToHide   = $(slider).find('[data-id='+prevImageNumber+'] img');
            $(slider).attr('data-image',imageNumber);
            var elementToShow   = $(slider).find('[data-id='+imageNumber+'] img');
            changeEffects(elementToHide,elementToShow);

            $(slider).find('a').removeClass('active');
            $(slider).find('a[data-id='+imageNumber+']').addClass('active');                
        }

        var nextImage = function(){
            sliders.each(function(){

               if ($(this).attr('data-passNext') || $(this).attr('data-stop') ){
                   $(this).removeAttr('data-passNext');
               }else{
                   var imageNumber = 0;
                   if ($(this).attr('data-image')){
                    var imageNumber = parseInt($(this).attr('data-image'));    
                   }
                   imageNumber = imageNumber +1;
                   var elementsCount = parseInt($(this).attr('data-count'));
                   if (imageNumber>elementsCount){
                       imageNumber=1;
