## Lightbox-only API for advanced usage

You can also choose to import only the Lightbox.

To use the Lightbox only, you'll need to handle the open state by yourself:

```js
import { Lightbox } from "react-modal-image";

// ...

const closeLightbox = () => {
  this.state.open = true;
};

// ...

{
  this.state.open && (
    <Lightbox
      medium={urlToLargeImageFile}
      large={urlToHugeImageFile}
      alt="Hello World!"
      onClose={this.closeLightbox}
    />
  );
}
```

| Prop      | Type       | Description                                             |
| --------- | ---------- | ------------------------------------------------------- |
| `onClose` | `function` | Will be invoked when the Lightbox requests to be closed |
