title: Joomla menu with custom page display option
body: <p>My web site layout has images to the right of most pages. I want to configure which image to show in the menu item settings.</p>
  
  <p>It seems that the proper place to configure the image would be the page display options for the menu item. I don't want to use the Page Class option as this would require changing the template for every new image.</p>
  
  <p>Is there a way I can add a custom Page Display Option (for the image url) and read that from the template?</p>
