Hello, @TFS,
1- Actually, by default, the image will show but if you add any content the image will be removed automatically, and your content will start to appear as you can see in this image: https://postimg.cc/LqCNxZ5C
2- In order to solve your issue simply go to the Dashboard >> XStore >> Theme Settings >> Theme Custom CSS >> Global and paste the below code at the bottom of the CSS box there.
.cart-checkout-light-footer .footer{padding:20px 0px !important;}
Then save settings and check back to your site after clearing the browser cache.
