Open Graph Warnings That Should Be Fixed
Inferred Property The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
og:image should be larger Provided og:image is not big enough. Please use an image that's at least 200x200 px. Image 'http://thecrewenews.co.uk/wp-content/uploads/Monster-Mash-2012.jpg' will be used instead.
Just to inform..... Images are BIGGER than 200x200 px so this issue is ruled out.
