+You can convert a **PixelMap** into a **ArrayBuffer** and save the **ArrayBuffer** to your database.

+
+## What If There is No Return Value or Error Captured After getAlbums Is Called?
+
+Applicable to: OpenHarmony SDK 3.2.5.3, stage model of API version 9
+
+The **ohos.permission.READ_MEDIA** permission is required for calling **getAlbums**, and this permission needs user authorization. For details, see OpenHarmony [Application Permission List](../security/permission-list.md).
+
+1. Configure the required permission in the **module.json5** file.
+     
+   ```
+   "requestPermissions": [
+     {
+       "name": "ohos.permission.READ_MEDIA"
+     }
+   ]
+   ```
+
+2. Add the code for user authorization before the **MainAbility.ts -> onWindowStageCreate** page is loaded.
+     
+   ```
+   private requestPermissions() {
+   let permissionList: Array<string> = [
+     "ohos.permission.READ_MEDIA"
+   ];
+   this.context.requestPermissionsFromUser(permissionList)
+     .then(data => {
+       console.info(`request permission data result = ${data.authResults}`)
+     })
+     .catch(err => {
+       console.error(`fail to request permission error:${err}`)
+     })
+   }
+   ```
