Scrolllider Woo Theme

Hi All,
I am somewhat of a newbie to WordPress but have a lot of experience with Joomla so I am transitioning and learning, so please bare with me.

I am using a Woo Theme called Scrollider and in that theme they have a widget called Woo Feedback, right now we are using them as a testimonial section with multiple entries from different sources. There is supposed to be an image of the person beside the testimonial. Right now it is just the default mystery man image. The widget uses gravatars but the problem I’ve run into is most of these people do not utilize gravatars.

I need to insert custom images for EACH of these entries but do not know how to go about doing that.

I tried editing the widget-woo-feedback.php but that didn’t work, or at least I didn’t go about doing that correctly. I was going to edit line 109 but I don’t think that we correct. I’ve been in contact with Woo Themes but have not had much luck. So I am turning to you you all.

The site i’m working on is https://www.daveconklin.org. I have some other issues but lets just take this one step at a time.
