Facebook Thumbnail – Open Graph Error

og:image should be larger:	Provided og:image is not big enough. Please use an image that's at least 200x200 px. Image 'http://www.tubersstudio.com/wp-content/uploads/2013/08/leslie-lewis-pic2-700x390.jpg' will be used instead.
Parser Mismatched Metadata:	The parser's result for this metadata did not match the input metadata. Likely, this was caused by the data being ordered in an unexpected way, multiple values being given for a property only expecting a single value, or property values for a given property being mismatched. Here are the input properties that were not seen in the parsed result: 'fb:title, fb:description, fb:url, fb:image, fb:type, fb:site_name'

Please help me out its my first wordpress website !
