title: Images that are in App_Data folder not shown in browser
body: <p>When I set image URL property to asp image control that is in App_Data folder, image is showing in page design view but not in browser.</p>
  
  <pre><code>&lt;form id="form1" runat="server"&gt;
  &lt;div&gt;
      &lt;asp:Image ID="Image1" runat="server" ImageUrl="~/App_Data/p3.jpg" /&gt;
  &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>It seems to be straightforward, but it's not showing the image.</p>
