my site http://goo.gl/aWQnd9
Opencart 1.5.5.1
I use this codes for dynamically get properly product images
<meta property="og:image" content="<?php echo $thumb; ?>"/>
or
<meta property="og:image" content="<?php echo _GET['image] ?>"/>
or
<meta property="og:image" content="<?= $_GET['image'] ?>" />
But with no result. Every time Fb shows store logo and proper title with proper description, but when I try to share product pages via addthis.com extension, fb shows store logo instead of product images.
What to do?
