title: Windows 8 App: Why must I specify ms-appx:/// in my image source URL?
body: <p>I've been looking at the <a href="http://code.msdn.microsoft.com/0f5d56ae-5e57-48e1-9cd9-993115b027b9" rel="noreferrer">XAML Images sample project</a> and the XAML to load an image in that sample looks like this:</p>
  
  <pre><code>&lt;Image Source="Assets/image1.jpg"/&gt;
  </code></pre>
  
  <p>However, in my own project I find that I cannot load any images like that.  If I try I get E_NETWORK_ERROR when I handle the ImageFailed. Instead, I discovered that I have to use the ms-appx:/// prefix like this:</p>
  
  <pre><code>&lt;Image Source="ms-appx:///Assets/image1.jpg"/&gt;
  </code></pre>
  
  <p>Then it works.  Any ideas what's different about my project vs the sample that would cause this?</p>
