Round images inside a table visual

Hi All,

Im trying to recreate something i saw in a tableau dashboard in power bi. the concept is: You select a person in a dropdown menu, and the image on the page chance to the correct person. I got this working, but the pictures show square, just how i load them in.

I would like to make the images round instead of square. 

My inspiration came from the upper part of this visual: https://datasaurus-rex.com/gallery/gotviz-mkiii

I also used the same data to try my concept before using actual people. 

Here is my PBIX: https://1drv.ms/u/s!AgnVgd15_ye0hHVHQkcj2O_EhE-S

Note: The first 5 people (except accident) have a picture loaded in. 

Thanks in advance!
