Use the Testimonial addon to add quotes into your web page. You can add an avatar, and even customize the orientation of the testimonial (left, centered or right)
Do not dwell in the past, do not dream of the future, concentrate the mind on now. Let reality be reality. Let things flow naturally. Do not dwell in the past, do not dream of the future.
To add multiple testimonials in a slideshow, use the Testimonial Pro addon. Just like the Testimonial addon, you can configure various elements like avatar, orientation and many other settings.
