Employee widget - how to resize the image


I’m would like to resize the image of my employees on my home page. Please can you let me know how I do it. I would preferably like the image cut off to increase the height.

Please let me know if you can help.

here is a link to my site.



Please try to use square 400×400px images, then you should get avatars like on Sydney demo site here:

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
