that's fine. You can do the outside style by yourself.
multiple= {true} means that after you click on the upload box, you can choose one or more pictures at a time, and false can only upload them one by one

class ImagePickerExample extends React.Component {
  state = {
    files: [],
  }
  onChange = (files, type, index) => {
    console.log(files, type, index);
    this.setState({
      files,
    });
  }

  render() {
    const { files } = this.state;
    return (
      <div>
        <ImagePicker
          files={files}
          onChange={this.onChange}
          onImageClick={(index, fs) => console.log(index, fs)}
          selectable={files.length < 1}
          accept="image/gif,image/jpeg,image/jpg,image/png"
        />
      </div>
    );
  }
}

ReactDOM.render(<ImagePickerExample />, mountNode);

I don't understand. Can I paste the code and page?
