title: Editing Tumblr theme's HTML to accommodate transparency
body: <p>I have a Tumblr blog, and I'm using the <a href="http://effectortheme.tumblr.com/" rel="nofollow">Effector</a> theme. I like it, but unfortunately it colors <a href="http://droosy.tumblr.com/post/49381495718" rel="nofollow">the backgrounds of all partially transparent images black</a>. Is there any way I can edit the theme's HTML so that it makes transparent backgrounds white? I looked through the code already, but I think I need someone more familiar with HTML to give me advice.</p>
  
  <p>Thanks!</p>
