title: Animate a sprite by using two images
body: <p>I would have thought this was a common desire, but I'll be damned if I can find this.</p>
  
  <p>I simply want to Animate an image by swapping two images back and forth. I tried StoryBoard, but apparently you can't change the source in a storyboard.  The only answer I can come up with is a Timer, which I don't think is the best way.</p>
  
  <p><strong>Edit:</strong> <a href="https://stackoverflow.com/questions/2783619/how-do-i-animate-image-content-in-wpf">How do I animate image content in WPF?</a> Came up in the "Similiar Questions" window.  And while this will do what I want, it is "hackish" as the OP of it says, and it only swaps two images, what if I wanted a whole sequence of 10 or 20 or 100.</p>
