title: Open scaled image file in WP 8.1 app from LocalCache
body: <p>I develop a Windows Phone 8.1 app that downloads some data from our server and copy these files into the <code>ApplicationData.Current.LocalCacheFolder</code> folder. There are also pictures in the folders with different scaling’s. For example:</p>
  
  <ul>
  <li>image.scale-100.png</li>
  <li>image.scale-140.png</li>
  <li>image.scale-240.png</li>
  </ul>
  
  <p>The problem is that I cannot access this files without passing the correct file name. If I try to open <em>image.png</em> it will fail. But if I try to open e.g. <em>image.scale-140.png</em> it works well. </p>
  
  <p>If I insert the images into my project Folder as a resource the app decides which image has the correct scaling for the Display and choose them.</p>
  
  <p>Can I get my app to choose the right image automatically? Or must I determine the scaling manually and determine which images exists?</p>
