title: Image XAML tag (Win8) not working with some paths
body: <p>The Source attribute of the Image tag works only with the files which were added to the 'Assets' folder in the Solution Explorer.</p>
  
  <p>I've got two files in the Assets directory: Logo.png and Logo2.png, but only Logo.png is added to 'Assets' in the Solution Explorer. This image works properly:</p>
  
  <pre><code>&lt;Image Source="/Assets/Logo.png"/&gt;
  </code></pre>
  
  <p>while this image doesn't show up:</p>
  
  <pre><code>&lt;Image Source="/Assets/Logo2.png"/&gt;
  </code></pre>
  
  <p>File paths like 'C:\Users\user\Pictures\img.jpg' don't work either.
  Is it possible to access images which are not specified in the 'Assets' folder in the Solution Explorer?</p>
  
  <p>EDIT:</p>
  
  <p>Here is what I do:</p>
  
  <ol>
  <li>Create new project in VS2012: Visual C# -> Windows Store -> Blank App (XAML)</li>
  <li>Open MainPage.xaml</li>
  <li>Choose Image from Toolbox and draw an image element in the Design mode</li>
  <li>The only working value for the Source attribute is '/Assets/Logo.png'. These are not working: 'C:\images\img.jpg', '/Assets/Logo2.png', 'Project_name;component/Assets/Logo.png', 'Project_name;component/Assets/Logo2.png', etc.</li>
  </ol>
