title: Resize images in UIWebView to viewport size
body: <p>I'm displaying HTML with some images inside a UIWebView in my iPhone App. 
  When the images are wider than the viewport of the iPhone I get horizontal scrollers which I don't want because its mostly about the text not the images.</p>
  
  <p>Is there a way to resize images displayed inside the UIWebView according to the width (best: even if the device is rotated)?</p>
