title: How can I create overlapping images that reveal themselves as you scroll
body: <p>I am looking to create a scrolling effect similar to that shown here: <a href="http://www.seaham-hall.co.uk/" rel="nofollow">http://www.seaham-hall.co.uk/</a></p>
  
  <p>However I am unable to achieve the desired effect, and inspecting the sites code gives me no hints. Quite difficult to google for as it is also quite difficult to describe. The closest I can get to finding a solution is this JSFiddle:</p>
  
  <p><a href="http://jsfiddle.net/xtyus/1/" rel="nofollow">http://jsfiddle.net/xtyus/1/</a></p>
  
  <pre><code>(function($){
      /* Store the original positions */
      var d1 = $('.one');
      var d1orgtop = d1.position().top;
      var d2 = $('.two');
      var d2orgtop = d2.position().top;
      var d3 = $('.three');
      var d3orgtop = d3.position().top;
      var d4 = $('.four');
      var d4orgtop = d4.position().top;
  
      /* respond to the scroll event */
      $(window).scroll(function(){
          /* get the current scroll position */
          var st = $(window).scrollTop();
  
          /* change classes based on section positions */
          if (st &gt;= d1orgtop) {
              d1.addClass('latched');
          } else {
              d1.removeClass('latched');
          }
          if (st &gt;= d2orgtop) {
              d2.addClass('latched');
          } else {
              d2.removeClass('latched');
          }
          if (st &gt;= d3orgtop) {
              d3.addClass('latched');
          } else {
              d3.removeClass('latched');
          }
          if (st &gt;= d4orgtop) {
              d4.addClass('latched');
          } else {
              d4.removeClass('latched');
          }
      });
  
  })(window.jQuery);
  </code></pre>
  
  <p>However I am not sure that is going in the right direction, this pulls images up and covers the previous image, but notice on the Seaham Hall site the images don't appear to move up at all, they are stationary and become revealed as you scroll.</p>
  
  <p>How do I recreate this effect? My initial thought was to have the first image shrink as you scroll from 1000px down to 0px, and the second image grow to 1000px, and as you continue to scroll this image then shrinks and the third grows, and so on. However this means that after the first image all the other images have a starting size of 0px and there would technically be no scrolling on the page to begin with, so that is an issue.</p>
  
  <p>My second thought is that perhaps the second image is fixed to the page, the first image slides up revealing the second as you scroll, the second image would not appear to move. Once the first image has gone off the top of the page the second image is detached from the page and allowed to move up with scrolling, while the third image is attached and revealed as the second moves up, this would give the exact effect seen in the Seaham website but I have no clue of it is the correct answer.</p>
  
  <p>If anyone can point me to tutorials or a JSFiddle with a basic concept I can probably figure it out from there. Just stumped what direction to approach this from. </p>
