Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .

If I understand correctly then you need to use og: * meta tags, here you can read and find examples http://ogp.me/ (English)
Here is an example of changing the picture.
<meta property="og:image" content="http://ia.media-imdb.com/images/rock.jpg" />
Ps Some services can cache these meta tags and need to refer to a special API method to update information about a page with a modified tag (in case of VK)
