I've followed the steps required for my client do exactly that, but somehow it's still not working. This is in reference to this earlier question
I wrote the Open graph code in the head section and tested and approved on Facebook debugger. I even specified height and width in the og code.

<meta property="og:image:type" content="image/jpeg" />
<meta property="og:image:width" content="200" />
<meta property="og:image:height" content="200" />Whilst it works fine on everything I've tested, when my client typed www.kessservices.co.uk into her iPhone 6 on the Facebook app she sent me this screenshot!
