title: Click to enlarge on tumblr
body: <p>I have a tumblr blog on which I post short webcomic stories. I want that when I post a few pages in a single post, they appear small, but when I click it enlarges and one can browse through the comic.</p>
  
  <p>I would like to have something similar to <a href="http://bastienvives.blogspot.fr/2015/05/samedi-lorsquon-fait-la-saison-dans.html" rel="nofollow">this</a>.</p>
  
  <p>How can I set it up?</p>
