title: How to dynamically download and display images in Windows8 metro app
body: <p>I get image URL at runtime from the xml file reader. This image URL is pass to the below method to download it dynamically.</p>
  
  <pre><code> public void Display_Image(string MyURL)
    {
             BitmapImage bi = new BitmapImage();
             bi.UriSource = new Uri(this.BaseUri, MyURL);
             Img_Poster.Source = bi;
    }
  </code></pre>
  
  <p>But this doesn't work. I don't get any image source. The above code works fine with static URL provided at compile time. What do I need to do more?</p>
