How to update facebook open graph image

facebook, facebook-opengraph

Solution

If you're too lazy to go to that link, you can `POST` an ajax request with the url you are trying to clear:

$.post(
    'https://graph.facebook.com',
    {
        id: 'http://www.site.com/my/share/url/',
        scrape: true
    },
    function(response){
        console.log(response);
    }
);

Problem

Say if you have set the facebook image for your webpage via the meta tag of the open graph protocol like this: `<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>` If you want to replace/update the image with another image of the same name `rock.jpg`, how do you get facebook to update your image accordingly with the new image when you share the page? Forcing facebook to fetch your page's data with this link http://developers.facebook.com/tools/debug won't update the image.
