Thread:Extension talk:AddThis/Pin It button

I am trying to add a 'pin it' button to my wiki site. I need to customise the code so it finds the media, description, title, url and video information from the page. So far the code I have is: getFullURL) . '&media='&description== &is_video=" class="pin-it-button" count-layout="horizontal"> I can send the url, but what code do I use to grab the media, description and video information? If you have any idea that would be AMAZING! I'm really stuck. Thanks
