        Copy a image URL here

          )}

Advanced

You might want to customized such as

as your final view, instead of tags, you can use image prop to replace any React element as you wish!

For example, using styled-components:

`js import styled from 'styled-components';

const PreviewImg = styled.div
background-image: url(${props => props.src});
width: 100%;
height: 300px;
background-size: contain;
background-repeat: no-repeat;
;

class Demo extends React.Component { ...

render() { const {value} = this.props; return (


                  src={value}
          image={props => } // change to your customized component
          loading={() => Loading...
}
          error={() => Error
}
          />


    );
  }
}
