How to change image size on experts page using jobify theme?

Having a issue changing the image sizes of experts on http://medhire.com.au/expert-2/
If you notice the images are extra large and distorted I tried activating custom layout and changing there but comes back with error page do to jobify theme.
I just want the image sizes to be like yours in the example.
