We don’t support the featured image in the shortcode. But here’s some CSS to help you getting that form looking good on your pages:
#give-donation-level-radio-list>li {
display: inline-block;
margin: 0 25px 0 0;
}
Then in your theme stylesheet on line 653 it looks like you’re forcing all forms to have text-align: center
Remove that and the form will look more like this:
