title: Disable Image caching in WP7
body: <p>I am having a horrible time with the automatic image caching by WP7 platform.</p>
  
  <p>I made a very simple app (I mean real simple). They have <strong>2 images already added in solution</strong> as content of pix dimension 1280 x 2000
  Here is XAML</p>
  
  <pre><code>&lt;Grid x:Name="LayoutRoot" Background="Transparent" ManipulationCompleted="ImageHolder_ManipulationCompleted"&gt;
      &lt;Image x:Name="ImageHolder" /&gt;
      &lt;TextBlock x:Name="MemoryUsage" /&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>My .cs</p>
  
  <pre><code>   ImageHolder.Source = null;
          if (i % 2 == 0)
              ImageHolder.Source = new BitmapImage(new Uri("image002.jpg", UriKind.Relative));
          else
              ImageHolder.Source = new BitmapImage(new Uri("image001.jpg", UriKind.Relative));
          i++;
  
     MemoryUsage.Text = "Device Total Memory = " + (long)DeviceExtendedProperties.GetValue("DeviceTotalMemory") / (1024 * 1024)
              + "\nCurrent Memory Usage = " + (long)DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage") / (1024 * 1024)
              + "\nPeak Memory Usage = " + (long)DeviceExtendedProperties.GetValue("ApplicationPeakMemoryUsage") / (1024 * 1024);
  </code></pre>
  
  <p>Memory usage is very high is equal to the 2 images in raw bitmap size, though there should only be one such instance. Please help, I am in dire need.</p>
