title: Loading images from a directory inside XAP
body: <p>I want to load some images into a ListBox. These images are inside XAP.</p>
  
  <p>Someone tell me that I can use ResourceManager, but I don't know how to get a list for all images inside a folder like "/Assets/Images/".</p>
  
  <p>These images are added as Content.</p>
  
  <p>Any advice?</p>
