facebook metatag image not displaying properly

I am trying to share the webpage with facebook and other social accounts. In the meta page I have set the following.

 <meta property="og:site_name" content="www.hashgurus.com">
<meta property="og:title" content="Worldwide| countrywise | Top Twitter Trends hourly/daily">
<meta property="og:type" content="article">
<meta property="og:description" content="Top twitter trends worldwide |country - Topics and discussions, Tweets in your place. Share and analyse the twitter trends to promote your website/product .">
 <meta property="og:image" content="http://ift.tt/1LexmVT" />

but the image is not displayed properly although I have correctly set the image tag as seen above. Some other image is getting displayed. Not sure where that image is getting displayed from. This can be seen at

any pointers would be helpful.
