jQuery(document).ready(function($){
 
 $('body').append('<span id="body_loader"></span>');
     $('#body_loader').fadeIn(); 
 
 //In our jQuery function, we will first cache some element and define some variables:
 var $bg             = $('#background'),
     $bg_img         = $bg.find('img'),
     $bg_img_eq      = $bg_img.eq(0),
     total           = $bg_img.length,
     current         = 0,
     $next       = $('#next'),
     $prev       = $('#prev')
 
 $(window).load(function(){
     //hide loader
     $('#body_loader').fadeOut('fast', function(){
         init();
     }).remove(); 
 
 });
 
 var intervalID,
     play = $('#play'),
     titleItem = $('.title-item');   
 
 //shows the first image and initializes events
 function init(){
     //get dimentions for the image, based on the windows size
     var dim = getImageDim($bg_img_eq);
     //set the returned values and show the image
     $bg_img_eq.css({
         width   : dim.width,
         height  : dim.height,
         left    : dim.left,
         top    : dim.top
     }).fadeIn('normal');
 
     //resizing the window resizes the $tf_bg_img
     $(window).bind('resize',function(){
         var dim = getImageDim($bg_img_eq);
         $bg_img_eq.css({
             width   : dim.width,
             height  : dim.height,
             left    : dim.left,
             top     : dim.top
         });
     });
 
     var activeTitle = $bg_img_eq.attr('title');
         titleItem.html(activeTitle);
         titleItem.html(function(){
             var text= $(this).text().split(" ");
             var last = text.pop();
             return text.join(" ")+ (text.length > 0 ? " <span class='word-last'>"+ last + "</span>" : last);
         });
 
     play.bind('click', function() {
         if($(this).hasClass('pause')) {
             clearInterval(intervalID);
             $(this).removeClass('pause').addClass('play');
         } else {
             $(this).addClass('pause').removeClass('play');
             intervalID = setInterval("$('#next').trigger('click')", 2000);
         }
 
     });
 
     //click the arrow down, scrolls down
     $next.bind('click',function(){
         if($bg_img_eq.is(':animated'))
             return false;
             scroll('tb');
     });
 
     //click the arrow up, scrolls up
     $prev.bind('click',function(){
         if($bg_img_eq.is(':animated'))
         return false;
         scroll('bt');
     });
 }
