How does Vkontakte parse sites? [resolved]

Question

Programming

When you post a link to a third-party resource on VKontakte, it automatically loads the page title and picture from this site.
Is it possible to specify which image on the page to select?

The bottom line is that I always have one main picture on my page, it is the largest in size and its alt almost coincides with the title, but VK takes it only in 20% of cases, and in other cases it takes the site logo.
Is it possible to somehow influence this?

Answer 1

<meta property="og:image" content="http://domain.name/img/vkontakte.png">
200x200 px recommended.

vk.com/pages?oid=-1&p=%D0%9F%D1%83%D0%B1%D0%BB%D0%B8%D0%BA%D0%B0%D1%86%D0%B8%D1% 8F_%D1%81%D1%82%D0%BE%D1%80%D0%BE%D0%BD%D0%BD%D0%B8%D1%85_%D1%81%D1%82%D1%80% D0%B0%D0%BD%D0%B8%D1%86
