Image link in lightbox

Hello, I have followed your instructions from here: [resolved] Assign external link to image

I have set thumbnail options to “Redirect to url”, if I choose same option in the album I am displaying, it does redirect to the url I have set for the image. However, if I choose “open lightbox” in album settings it opens the lightbox but image url is not displayed in address bar. Is this option only available in pro version?
