title: Loading new image each second
body: <p>I need to load each second (or two) new image. </p>
  
  <p>Following code doesn't work:</p>
  
  <pre><code>System.Threading.Thread.Sleep(2000);
  this.Image_LoadImage.Source = new BitmapImage(new Uri(@"D:\\connect2-1.gif"));
  System.Threading.Thread.Sleep(2000);
  this.Image_LoadImage.Source = new BitmapImage(new Uri(@"D:\\connect3-1.gif"));
  </code></pre>
  
  <p>What I see is that the app sleeps for 4 seconds and then the second image appears.</p>
  
  <p>How can i do it?
  Thanks.</p>
