Im tryng to make the Galleria template to "auto rotate"

    jQuery.noConflict();
jQuery(document).ready(function($){

$('.sigProGalleriaLink').click(function(event){

event.preventDefault();

// Prevent clicks upon animation
if($(':animated').length) return false;

// Assign element
var el = $(this);

// Parent container
var outerContainer = el.parent().parent().parent().parent().parent();
var placeholderContainer = outerContainer.find(".sigProGalleriaPlaceholderContainer div:first");

// Placeholder elements
  var targetLink = placeholderContainer.find("a:first");
  var targetTitle = placeholderContainer.find("p:first");
  var targetImg = targetLink.find("img:first");

  if(targetLink.hasClass('sigProGalleriaTargetLink')){

// Source elements
  var sourceLinkHref = el.attr("href");
  var sourceLinkTitle = el.attr("title");
  var sourceImage = el.find("img:first");
  if(el.find("span:nth-child(2)")){
  var sourceTitle = el.find("span:nth-child(2)").find("b:first").html();
  } else {
  var sourceTitle = false;
  }

placeholderContainer.animate({'opacity':0},300,function(){
targetImg.attr("src",sourceLinkHref);
targetImg.load(function(){
targetImg.attr("title",sourceImage.attr("title"));
targetImg.attr("alt",sourceImage.attr("alt"));
targetLink.attr("href",sourceLinkHref);
targetLink.attr("title",sourceLinkTitle);
if(targetTitle.hasClass('sigProGalleriaTargetTitle') && sourceTitle) targetTitle.html(sourceTitle);
placeholderContainer.animate({'opacity':1},600);
});
});

  }

// Set class for current thumb
var thumbs = outerContainer.find("ul:first").find("a");
thumbs.each(function(){
if($(this).hasClass('sigProLinkSelected')){
$(this).removeClass('sigProLinkSelected');
}
});
el.addClass('sigProLinkSelected');

});

});

Im tryng to change it, so the animation occur's automatically (auto rotates) instead of the need to being clicked.

Thanks
