title: How to set Startup directory to a Image in xaml
body: <p>Sorry for bad describe in the title. I have a image in "C:\Users\aUser\Desktop\Program\Image\Image.png" 
  But my program is in the same folder with the Image. I can set the Directory manually <code>&lt;Image Source="C:\Users\aUser\Desktop\Program\Image.png"</code> But when the parent directory is moved, the code will no longer work. So how can I set the Source of the image that in the child folder without use of the code behind 
  <code>Image.Source = new BitmapSource(new Uri(AppDomain.CurrentDomain.BaseDirectory + @"\Image\Image.png")</code>
