Meta tags for Open Graph - Facebook can't create thumbnail

问题

1. These are the meta tags that I use (I hope am using them right). What do you use mostly?

2. Also I have a problem when sharing my website on facebook. the og:image is for forcing facebook to use an image of my preference as a thumbnail. Instead of that facebook is using a wrong image and marked it as "safe_image" (safe_image.php). Why is this happening?

   <meta property="og:title" content="Myname - Best Products in Town">
   <meta property="og:type" content="Product">
   <meta property="og:url" content="http://www.mybestproducts.com/">
   <meta property="og:site_name" content="Myname">
   <meta property="og:description" content="Selling the best products">
   <meta property="og:image" content="images/mylogo.png">
   <meta property="og:image:width" content="550">
   <meta property="og:image:height" content="550">
   

Also I read this one first : FB OpenGraph og:image not pulling images (possibly https?)

But since I dont use https I don't think it's my case. So you what you think guys? Thank you all in advance

回答1:

The reason in my case was because there was a temporary cashing problem since my domain was linked to my facebook account for many years before linking it to an actual site. I had to wait for many days.
