   Simple Captcha is a very simplified captcha.
  
   *show_session_captcha* method will return the image, the label and the text box.
   This method should be called from the view within your form as...
  
   <%= show_session_captcha generate_captcha_url %>
  
   <b>Label:</b>
  
   default label is "type the text from the image", it can be modified by passing :label as
  
   <%= show_session_captcha(generate_captcha_url, :label => "new captcha label") %>.
