title: Test to see if an image exists in C#
body: <p>I am writing a diagnostic page for SiteScope and one area we need to test is if the connection to the file/media assets are accesible from the web server.  One way I think I can do this is load the image via code behind and test to see if the IIS status message is 200.  </p>
  
  <p>So basically I should be able to navigate to within the site to a folder like this: /media/1/image.jpg and see if it returns 200...if not throw exception.</p>
  
  <p>I am struggling to figure out how to write this code.</p>
  
  <p>Any help is greatly appreciated.</p>
  
  <p>Thanks</p>
