Add og:image:secure_url meta tag

I have a https website, and after much hair pulling wondering why facebook was not pulling any of my images correctly I've identified it as an issue with https.

I'm sorry if this has been addressed elsewhere, (I have looked) but what is the solution for getting metadata to point to og:image:secure_url instead of og:image

I'm not very good at coding and I'm finding a lot of the hook solutions need to be broken down for me before i can attempt to implement them.

Since the whole website is https I'm happy to replace the og:image meta entirely.
