## Image
Besides the native features of img, support lazy load, custom placeholder and load failure, etc.

### Basic Usage

:::demo Indicate how the image should be resized to fit its container by `fit`, same as native [object-fit](https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit)。
```html
<div class="demo-image">
  <div class="block" v-for="fit in fits" :key="fit">
    <span class="demonstration">{{ fit }}</span>
    <el-image
      style="width: 100px; height: 100px"
      :src="url"
      :fit="fit"></el-image>
  </div>
</div>

<script>
  export default {
    data() {
      return {
        fits: ['fill', 'contain', 'cover', 'none', 'scale-down'],
        url: 'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg'
      }
    }
  }
</script>
```
:::

### Placeholder

:::demo Custom placeholder content when image hasn't loaded yet by `slot = placeholder`
```html
<div class="demo-image__placeholder">
  <div class="block">
    <span class="demonstration">Default</span>
    <el-image :src="src"></el-image>
  </div>
  <div class="block">
    <span class="demonstration">Custom</span>
    <el-image :src="src">
      <div slot="placeholder" class="image-slot">
        Loading<span class="dot">...</span>
      </div>
    </el-image>
  </div>
</div>

<script>
  export default {
    data() {
      return {
        src: 'https://cube.elemecdn.com/6/94/4d3ea53c084bad6931a56d5158a48jpeg.jpeg'
      }
    }
  }
</script>
```
:::

### Load Failed

:::demo Custom failed content when error occurs to image load by `slot = error`
```html
<div class="demo-image__error">
  <div class="block">
    <span class="demonstration">Default</span>
    <el-image></el-image>
  </div>
  <div class="block">
    <span class="demonstration">Custom</span>
    <el-image>
      <div slot="error" class="image-slot">
        <i class="el-icon-picture-outline"></i>
      </div>
    </el-image>
  </div>
</div>
```
:::

### Lazy Load

:::demo Use lazy load by `lazy = true`. Image will load until scroll into view when set. You can indicate scroll container that adds scroll listener to by `scroll-container`. If undefined, will be the nearest parent container whose overflow property is auto or scroll.
```html
<div class="demo-image__lazy">
  <el-image v-for="url in urls" :key="url" :src="url" lazy></el-image>
</div>

<script>
  export default {
    data() {
      return {
        urls: [
          'https://fuss10.elemecdn.com/a/3f/3302e58f9a181d2509f3dc0fa68b0jpeg.jpeg',
          'https://fuss10.elemecdn.com/1/34/19aa98b1fcb2781c4fba33d850549jpeg.jpeg',
          'https://fuss10.elemecdn.com/0/6f/e35ff375812e6b0020b6b4e8f9583jpeg.jpeg',
