I need a client site to display the thumbnails whenever someone copies and pastes any link from the site. I've researched and found a lot about SEO with facebook , this site was meant to use Open Graph Protocol , but the example was just like an image.
How do I get it configured (can be a code in javascript or even php) so that any link that someone else shares appears thumbnail regardless of whether it is android, iphone or whatsapp web?
OBS: It also has to take into account that I use php with include in my pages, so the header is only one for the whole site, so it is not possible to include page by page. / p>
