Social Networks Auto-Poster: SNAP - how to understand what picture the plugin drags into the publication?
I use vodpress, I search VK, I use post type "post text with an "attached" link"
So, this is often the first picture or a preview of the post, but suddenly it can be some third picture or the post goes without a picture at all. Please help me figure out how to take control over which picture goes into the post, otherwise it’s some kind of horror, you need to partially publish, and then supplement

Answer 1

Usually social networks / messengers pull the image from the og: image (OpenGraph image) tag of each specific page. You can put it down manually, you can through plugins.
