[Plugin: Popular Widget] Thumbnail image error

Hi,

I downloaded your helpful plugin. I modified it a bit for visual purposes.

I’m having one particular problem. The thumbnails of the users who have logged in using “social login” plugin appear as the thumbnails of all the users on the page where they have made a comment.
