Cropped Image on share

Hi there

I installed the OpenGraph and now it looks like it’s sharing with a picture and description, however my picture appears to be cropped.

Please have a look and test with http://www.luizavarovici.co.uk/portfolio_page/carnations-3/

and try to use the faceboook share to see the cropped image.

Can you please advise.

Kind regards
Luiza Varovici
