How to solve the problem with photos in reposts?

Question

WordPress

I do everything as usual, what the problem is I can not understand. It looks like the WordPress template is some kind of very competent, but I did all the settings as on all previous sites. Usually, during a repost, I insert a link into the text, a comment, and a photo is automatically generated, one of those in the article on the site, where the link actually leads. In most cases, this is either the first photo in the article or a thumbnail of the article itself. Here is this:

I tried it on all sites, everywhere it's so clumsy. Instead of a photo from the article, it displays an empty avatar, I searched on the site where it is located in order to delete it altogether, I did not find it.
Please advise how to fix this problem so that beautiful pictures from the article are displayed in reposts, and not this ugliness.
