The `Animation node` sends an animated GIF or video to the chatbot from a local file or from a URL or from a Buffer passed by an upstream node (the simplest way to use it to chain with to `File node` or a `Http node`).

To programmatically send an animation with a `Function node`

```javascript
msg.payload = '/my_dir/my_image.gif';
```

or

```javascript
msg.payload = {
  caption: 'I am the caption',
  image: 'http://www.my_host.com/my_dir/my_image.gif'
};
```
