Images in Circle

Hi, I have configured GK5 to display testimonials with standard format and ‘joomla articles’ as data source.

I have selected source of image as intro image of joomla articles.

My question is how to display images (avatar) in circle like Google displays everywhere.

What and where should I do CSS overrides ?

Could You please post an url to your site?

I am working on local server at desktop, hence cannot provide you URL.

I’m using GAMAE joomla 2.5 template.

Sadly, till you will be able to show the site, even on a temporary server, I can't help much further.
