Question

MODX

<meta property="og:image" content="" />there is such a link to direct the upload of the image will be shared on the social network. I don't know how to load an image from the content. it is not covered by the tv parameter. Maybe somehow picking up the first image through php and calling it through the snippet.

Answer 1

So make a TV field (like a post thumbnail in Wordpress) and add pictures there and display them in og:image/ Well, or sort it out for yourself https://bezumkin.ru/sections/tips_and_tricks/2192/
