Facebook Sharing (and other Social Media) to Popup or Not?

Hello! As the image below shows, I have a Popup that displays an image, a title and a description. I’ve added the social share plugin, but my challenge, and, yes, I’ve seen other threads about this, is how do we share the specific image shown here?

  1. Am I making a mistake by having it share from a PopUp?
  2. Would it be better/easier for my MVP to share from its own page?
  3. It is possible at all to share the image to Facebook/Twitter/WhatsApp, etc? Or am I better off just letting them download the file and share themselves?

All suggestions and help are appreciated.

Thank you,

looking for the same answer, everywhere we see instructions on sharing URL,
I want users to share images+text to social media.

Looking forward to some help.
Thanks
