+### ImagePreview 调用方式调整
+
+Vant 4 中，`ImagePreview` 组件的调用方式也进行了调整，与 `ImagePreview` 组件的改动一致：
+
+```js
+// Vant 3
+ImagePreview(); // 函数调用
+ImagePreview.Component; // 组件对象
+
+// Vant 4
+showImagePreview(); // 函数调用
+ImagePreview; // 组件对象
+```
+
 ### 事件命名调整
 
 从 Vant 4 开始，所有的事件均采用 Vue 官方推荐的**驼峰格式**进行命名。

+图片放大预览，支持组件调用和函数调用两种方式。
 
-### 函数调用
+### 引入
 
-`ImagePreview` 是一个函数，调用函数后会直接在页面中展示图片预览界面。
-
-```js
-import { ImagePreview } from 'vant';
-
-ImagePreview(['https://fastly.jsdelivr.net/npm/@vant/assets/apple-1.jpeg']);
-```
-
-### 组件调用
-
-通过组件调用 `ImagePreview` 时，可以通过下面的方式进行注册。
+通过以下方式来全局注册组件，更多注册方式请参考[组件注册](#/zh-CN/advanced-usage#zu-jian-zhu-ce)。
 
 ```js
 import { createApp } from 'vue';
 import { ImagePreview } from 'vant';
 
-// 全局注册
 const app = createApp();
 app.use(ImagePreview);
-
-// 局部注册
-export default {
-  components: {
-    [ImagePreview.Component.name]: ImagePreview.Component,

-};
 ```
 
-在 `script setup` 中，可以通过以下方式使用：
+### 函数调用
 
-```html
-<script setup>
-  const VanImagePreview = ImagePreview.Component;
-</script>
+为了便于使用 `ImagePreview`，Vant 提供了一系列辅助函数，通过辅助函数可以快速唤起全局的弹窗组件。
 
-<template>
-  <!-- 中划线命名 -->
-  <van-image-preview />
-  <!-- 也支持大驼峰命名 -->
-  <VanImagePreview>
-</template>
+比如使用 `showImagePreview` 函数，调用后会直接在页面中渲染对应的图片预览组件。
+
+```js
+import { showImagePreview } from 'vant';
