title: Titanium: get png height without creating ImageView
body: <p>Is there a way to get a .png height without creating ImageView?</p>
  
  <p>The methods I found on google require createImageView first and then doing a .height.</p>
  
  <p>I want to avoid creating ImageView because I'm going to createImageView after I get the height of the png and perform some changes.</p>
  
  <p>Or rather, I will be using the height value during the var imagevariablename = Ti.UI.createImageView itself, so I can't using imagevariablename.height because the declaration of var imagevariablename is not done yet.</p>
