Hi John,
             I built a site by name http://www.srikanta-sastri.org/. Whenever I search the site out on Google search (world or India), the search results are quite specific and nicely ranked. But the site preview (the lens button at the end of the search result) almost never shows my website page's image. Ever..! It just shows a blank background with a central broken Jigsaw icon. Am I doing something wrong or what..? Please help me on this..Any advice would be welcome.

-With best regards
 Dr S.N.Bhagirath
