</SimpleForm>

this.handleClick = () => {
   cloudinary.openUploadWidget({
       cloud_name: 'demo',

       cropping: 'server'
    }, function(error, result) {
       return result;
   });
};

You'll have to implement a custom input for that.

Something like (haven't tested it):

class UploadPictureInput extends Component {
    handleClick = () => {
        cloudinary.openUploadWidget({
            cloud_name: 'demo',
            upload_preset: 'sh3432',
            cropping: 'server'
        }, (error, result) => {
            this.props.input.onChange(result);
        });
    }

    render() {
        return (
            <FlatButton
                style={styles.button}
                label="Upload Image"
                primary
                onClick={this.handleClick}
            />
        );
    }
}

And use this input in your form.
