# Image
Besides the native features of img, support lazy load, custom placeholder and load failure, etc.
<style lang="scss">

## 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)。
image/basic-usage
:::
## Placeholder
:::demo Custom placeholder content when image hasn't loaded yet by `slot = placeholder`
image/placeholder
:::
## Load Failed
:::demo Custom failed content when error occurs to image load by `slot = error`
image/load-failed
:::
## 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.
image/lazy-load
:::
## Image Preview
:::demo allow big image preview by setting `previewSrcList` prop.
image/image-preview
