Making items sharable on social media

Is there away to associate images with items so that they display on social media posts?

You’re talking about adding OpenGraph tags or Twitter card markup, right?

I’m aware of a couple user-written plugins that add these, like this one though I don’t have personal experience with them.

I don’t know. I really have no programming experience, and I can’t make sense of the Omeka user manual. I just want to be able to post links to my items on various social media platforms and have images pop up in the preview.
