title: Wordpress Custom Fields for og:image
body: <p>I am building a website in Wordpress and I am writing some Articles. When I share my post/article on Facebook, the wrong image appears (on the phone, as on the computer it seems that the image is chosen correctly). I have seen that Facebook needs the og:image tag and it needs to be called in the head metadata. As I do not have many options to add metadata to the page, I felt like using the <strong>Custom Fileds</strong> in Wordpress as being the cleanest way. As I am new to this and I am not sure I did it correctly, please guide me on how to call these custom fileds to the head metadata part of my page when it loads. I have attached a snip of my custom field here:
  <a href="https://i.stack.imgur.com/CPGS4.jpg" rel="nofollow noreferrer">custom custom field</a></p>
  <p>Please let me know if my thinking was correct or if I should use another method to accomplish this.
  Thank you very much.</p>
