  <p>where the width is  100%, and keeps scrolling infinitely left or right, but always having an image in the center no matter the browser resolution. This is what ive got so far</p>

  <p>the slideshow images have a width of 800px, the left most image has a margin-left of -25%... which sorta looks like it works in a 1280px screen size.... but doesnt look like its suppose to when i resize the window. </p>
  
  <p>Heres the slideshow code im using</p>
  
  <pre><code>$(document).ready(function() {
      //move he last list item before the first item. The purpose of this is if the user clicks to slide left he will be able to see the last item.
      $('#carousel_ul li:first').before($('#carousel_ul li:last')); 
  
  
      //when user clicks the image for sliding right        
      $('#right_scroll img').click(function(){
  
          //get the width of the items ( i like making the jquery part dynamic, so if you change the width in the css you won't have o change it here too ) '
          var item_width = $('#carousel_ul li').outerWidth() + 10;
  
          //calculae the new left indent of the unordered list
          var left_indent = parseInt($('#carousel_ul').css('left')) - item_width;
  
          //make the sliding effect using jquery's anumate function '
          $('#carousel_ul:not(:animated)').animate({'left' : left_indent},500,function(){    
  
              //get the first list item and put it after the last list item (that's how the infinite effects is made) '
              $('#carousel_ul li:last').after($('#carousel_ul li:first')); 
  
              //and get the left indent to the default -210px
              $('#carousel_ul').css({'left' : '-210px'});
          }); 
      });
  
      //when user clicks the image for sliding left
      $('#left_scroll img').click(function(){
  
          var item_width = $('#carousel_ul li').outerWidth() + 10;
  
          /* same as for sliding right except that it's current left indent + the item width (for the sliding right it's - item_width) */
          var left_indent = parseInt($('#carousel_ul').css('left')) + item_width;
  
          $('#carousel_ul:not(:animated)').animate({'left' : left_indent},500,function(){    
  
          /* when sliding to left we are moving the last item before the first list item */            
          $('#carousel_ul li:first').before($('#carousel_ul li:last')); 
  
          /* and again, when we make that change we are setting the left indent of our unordered list to the default -210px */
          $('#carousel_ul').css({'left' : '-210px'});
          });
  
  
      });});
  </code></pre>
  
  <p>Any ideas? thanks</p>
