title: The most appropriate bitmap class for the model
body: <p>I am writing a simple WPF application using MVVM.
  What is the most convenient class to retrieve bitmaps from <strong>models</strong> and further data binding: Bitmap, BitmapImage, BitmapSource?</p>
  
  <pre><code>public class Student
  {
      public &lt;type?&gt; Photo
      {
          get;
      }
  }
  </code></pre>
  
  <p>Or maybe I can somehow convert Bitmap to BitmapSource using ViewModel?</p>
