title: How do I create a fade-in load effect, one after another image
body: <p>I've got inspired by the thumb loading effect on <a href="http://www.marclagrange.com/timeline/" rel="nofollow">this</a> page, but honestly got no clue how to create such effect, on each thumb.</p>
  
  <p>Who could point me in the right direction, or even give me some lines of codes?</p>
  
  <p>I've seen some other topics related, but those won't work in a situation where many images will be loaded, one after another.</p>
  
  <p>Thanks!</p>
