title: how do you hide an image in Tumblr's permalink page?
body: <p>I want to have my own thumbnails for video posts on my main tumblr page....and show the video only in the permalink page with out the thumbnail.  </p>
  
  <p>here's an example site of what I'm trying to do: 
  <a href="http://devour.com/" rel="nofollow">http://devour.com/</a>  (not tumblr but same idea)</p>
  
  <p>I figured the best method is to post the thumbnail as a photo post, with the video embedded. Then hide the image in the permalink page.</p>
  
  <p>so my question is...how do I hide the image in the permalink page?</p>
