Newbie question Astra Theme – removing picture

Hi, for my personal website I use the wordpress Astra theme. I took the free design ‘hello, I’m Brian , I’m a freelance copywriter’ and imported the full site. Than I started editing but my problem is I can’t remove the picture of Brian on my home page under the footer. And since I’m not Brian, that’s pretty annoying. How do I fix this? Best regards, Martin
