Avatar of Reviews not showing

Hi,

I’ve installed your plugin and I’m using the free version. I like the simplicity it offers. It works fine but only the avatars of the client reviews do not show up. It only shows the name and date.
Can you help me find where the problem might be?

Also, how many reviews does the free version shows up? Because I have almost 400 reviews and it only shows 10 of them.

Looking for your response.
Thanks!
