When I share a post from my website on Facebook many times the thumbnail image is displayed small and other times it is displayed full screen. What I really want is for it to always be displayed full screen, I don't like it to be displayed this way
I want the image to always be shown complete, covering the entire publication, but I don't know how to achieve it. There are articles on my blog that when I share them on Facebook they are shown as I want, instead most are shown with the small image that is how I don't like it.
Code I'm currently using from Open Graph
