<script runat="server">

  void ScheduleCalendar_DayRender(object sender, DayRenderEventArgs e)
  {
    // Customize the caption for today's date.
    if(e.Day.IsToday)
    {
      // Create the content to render for today's date. Use the 
      // SelectUrl property to retrieve the script used to post
      // the page back to the server when the user selects the
      // date.
      string dayContent = "<a href=\"" + e.SelectUrl +
        "\"><img border=\"0\" alt=\"Today\" src=\"today.jpg\"/></a>";
      
      // Display the custom content in the date cell. 
      e.Cell.Text = dayContent;
    }
    
  }
  
</script>

Remarks

Use the SelectUrl property to retrieve the script used to post the page back to the server when the date being rendered is selected in a Calendar control. This property is typically used when you want to customize the content rendered for a date, but still want to retain the postback behavior.
