title: ASP.NET: Adding 'Watermark' to images on the fly
body: <p>I have seen great questions and answers regarding <a href="https://stackoverflow.com/questions/2235152/add-watermark-to-images-with-php">adding watermark on images with php</a></p>
  
  <p>I would like to do the same, this time with ASP.NET</p>
  
  <p>So here are a couple of questions.</p>
  
  <ol>
  <li>How can i do that with ASP?</li>
  <li>Is this process going to be a great overload for the server?</li>
  <li>Could i use an image for a watermark instead of simple text?</li>
  </ol>
