Setting a backgroundImage With React Inline Styles

I'm attempting to get to a static picture to use inside an inline background picture property inside React. Sadly, I've run up dry on the best way to do this.

Usually, I thought you just did as follows:

import Background from '../images/background_image.png';



var sectionStyle = {

  width: "100%",

  height: "400px",

  backgroundImage: "url(" + { Background } + ")"

};



class Section extends Component {

  render() {

    return (

      <section style={ sectionStyle }>

      </section>

    );

  }

}

This works for <img> tags. Can anyone describe the difference between the two?

Example:
<img src={ Background } /> works just fine.
