script Infinite-Scroll que se abra desde la pagina numero 5

[legom753]

Hola, estoy trabajando con infinitescroll (http://masonry.desandro.com/demos/infinite-scroll.html) y cada ves que bajo abre la pagina 2, osea de la Pag-1 a Pag-2 (así sucesivamente 3,4,5,6,etc ) Yo necesito que pase de la Pag1 a la Pag5 que se saltee la 2,3,4.

Este es el codigo que va en la pagina 1:

Código PHP:

  <nav id="page-nav">
  <a href="/sistema/noticias.php?noticia=2"></a>
</nav>
 
<script src="../js/jquery-1.7.1.min.js"></script>
<script src="../jquery.masonry.min.js"></script>
<script src="../js/jquery.infinitescroll.min.js"></script>
<script>
  $(function(){
    
    var $container = $('#container');
    
    $container.imagesLoaded(function(){
      $container.masonry({
        itemSelector: '.box',
        columnWidth: 100
      });
    });
    
    $container.infinitescroll({
      navSelector  : '#page-nav',    // selector for the paged navigation 
      nextSelector : '#page-nav a',  // selector for the NEXT link (to page 2)
      itemSelector : '.box',     // selector for all items you'll retrieve
      loading: {
          finishedMsg: '<b style=" font-size:16px; font-weight: normal;line-height: 33px;margin: 10px 0 -8px 0;z-index: 10;bottom: 0;left: 8px;background: none!important;color: #FFF;;opacity: 1;font-family: "HelveticaNeueW02-77BdCn 694066";text-transform: uppercase;text-shadow: 1px 1px 8px #000;filter: dropshadow(color=#000000,offx=2,offy=2);width: 356px;position: absolute;">No Hay Mas Fotos!',
          img: '/img/loading.gif'
        }
      },
      // trigger Masonry as a callback
      function( newElements ) {
        // hide new items while they are loading
        var $newElems = $( newElements ).css({ opacity: 0 });
        // ensure that images load before adding to masonry layout
        $newElems.imagesLoaded(function(){
          // show elems now they're ready
          $newElems.animate({ opacity: 1 });
          $container.masonry( 'appended', $newElems, true ); 
        });
      }
    );
    
  });
</script>
