how to control image sharing link on facebook og: open graph

[dengy]

I have following open graph on presta 1.6 sharing this link to a blog post http://brunchme.dk/da/blog/brunch-opskrift/eggs-benedict-brunch-opskrift i get three thumbnails none of them exist on that current page. It works well with my products. Is there a way to control which image to show or can i force a logo if not possible?

<meta property="og:title" content="{$meta_title|escape:'htmlall':'UTF-8'}"/>
<meta property="og:url" content="http://{$smarty.server.HTTP_HOST}{$smarty.server.REQUEST_URI}"/>
<meta property="og:site_name" content="{$shop_name|escape:'htmlall':'UTF-8'}"/>
<meta property="og:type" content="website">
<meta property="og:description" content="{$meta_description|escape:html:'UTF-8'}">
{if $page_name=='product'}
<meta property="og:image" content="{$link->getImageLink($product->link_rewrite, $cover.id_image, 'large')}">
        {else}
<meta property="og:image" content="{$img_ps_dir}logo.jpg" />

it uses logo on other pages than product page

take a look: http://brunchme.dk/img/logo.jpg

 

 

this file is empty, just white

this is why facebook uses other pictures.

I have the correct path to my logo now, but i'm having the same issue ?
