title: Dynamic background-image on body (ASP.NET)
body: <p>I have a situation where I have ~10-20 different background images in a folder. When my site loads I need to choose a specific one of these images based upon some values from the database.</p>
  
  <p>I thought about using <em>runat=server</em> on the body tag, and then adding the attributes dynamically on page_load, but everywhere I have read that suggestion people say it is a really bad idea...
  Also, I tried it, and it didn't work (however didn't debug it too much).</p>
  
  <p>How would one do this "the right way" ? :-)</p>
