addthis does not display product image on facebook

Hello, i`m using opencart 2.1.0.1 version with default theme.
And when i`m trying to share product from the website facebook addthis plugin does not grab and display product image in facebook posts.
The images are shown just with a few products, not for the other 98% of them.
Could you please give me and advice what i need to do to fix this.
My website is http://fishingbg.eu

Thank you for your reply and i`m not still sure what i`m searching for.
Please excuse me but i`m opencart newbie.
I have tried to use this kind of extension with a hope that it will be my salvation http://www.opencart.com/index.php?route ... n_id=22963 and after successful installation and reading "read me" file instruction i have done all the necessary in my opinion and nothing has changed.
Please give me some clues.

That extension should solve your problem. Be sure to clear your extension cache and rebuild it. Then view the source of any of your product pages and you should see og: tags added.
