I know this is from 2 years ago, but the input from 13698 is the best answer on the community
Hi Paul,
I'm facing the same issue. Added this code to my Marketo Landing page and still the image is not being pulled. This is so frustrating, I tried inserting it into the Custom Head area and into the Facebook OG area and it just doesn't work.
<meta property="og:image" content="http://www.marketo.com/_assets/uploads/what-is.PNG?20130620133033"/>
<meta property="og:image:width" content="200" />
<meta property="og:image:height" content="200" />
Do you think it's still the best answer another two years in?
Thanks,
Yulya
