Thumbnails blurry retina display testimonials

Hey blankonblank!

Thank you for visiting the support forum.

Please add this on functions.php to change the thumbnail size of the testimonial element:

add_filter('avf_testimonials_avatar_size', 'avf_adjust_testimonials_avatar_size' );

function avf_adjust_testimonials_avatar_size($avatar_size) {
	$avatar_size  = 'square';
	return $avatar_size;
}

Upload the images again or regenerate the thumbnails using this plugin: http://wordpress.org/plugins/regenerate-thumbnails/

Remove browser cache then reload the page a few times.

Regards,
Ismael
