title: Liferay Web Content Template : How to find out if image has been set?
body: <p>I have created a Liferay Web Content Structure and Template.
  This Structure contains an image that can or can not be set.
  If the image is not set then I do not want to render an IMG tag.</p>
  
  <p>How can I determine in my template if the picture is set / present ?</p>
  
  <p>Best regards,</p>
