### Lazy Load

Set `lazy` and `placehoulder` properties to implement the lazy load. 

```jsx live
<div style={{ height: 250, overflowY: 'scroll' }}>
  <p>Scroll up to make images into the view area.</p>
  <div style={{ height: 350 }}/>
  <Image lazy round src="https://github.com/wangdicoder/tiny-ui/blob/master/site/public/avatar/avatar3.png?raw=true" placeholder="https://github.com/wangdicoder/tiny-ui/blob/master/site/public/avatar/avatar3_blur.png?raw=true"/>
  <div style={{ height: 350 }}/>
  <Image lazy width={300} height={200} src="https://github.com/wangdicoder/tiny-ui/blob/master/site/public/avatar/plants.jpg?raw=true" placeholder="https://github.com/wangdicoder/tiny-ui/blob/master/site/public/avatar/plants_blur.png?raw=true"/>
  <div style={{ height: 100 }}/>
</div>
```
