# Device.getPhotos

> 함수형 API `fetchAlbumPhotos`로도 같은 기능을 쓸 수 있어요.

### 기능 설명

사용자의 앨범에서 사진 목록을 불러와요. 최대 개수와 해상도를 설정할 수 있고, 갤러리 미리보기·이미지 선택 등에 활용할 수 있어요.

사진첩 읽기 권한이 없으면 `FetchAlbumPhotosPermissionError`가 발생해요. `Device.getPhotos.getPermission()`으로 권한 상태를 확인하고, `Device.getPhotos.openPermissionDialog()`로 권한을 다시 요청할 수 있어요.

### 타입

```ts
Device.getPhotos(options?: FetchAlbumPhotosOptions): Promise<ImageResponse[]>;
```

**Params**

```ts
type FetchAlbumPhotosOptions = {
  /** 가져올 사진의 최대 개수예요. 기본값은 10이에요. */
  maxCount?: number;
  /** 사진의 최대 폭(px)이에요. 기본값은 1024이에요. */
  maxWidth?: number;
  /** 이미지를 base64로 반환할지 여부예요. 기본값은 false예요. */
  base64?: boolean;
};
```

**Response**

```ts
type ImageResponse = {
  id: string;
  dataUri: string;
};
```

### 에러

에러는 클래스로 던져져요 — `error instanceof FetchAlbumPhotosPermissionError`로 식별해요. 클래스는 `@apps-in-toss/web-framework`에서 import할 수 있어요.

| 에러 클래스                            | 설명                                                                            |
| --------------------------------- | ----------------------------------------------------------------------------- |
| `FetchAlbumPhotosPermissionError` | 사진첩 읽기 권한이 거부된 경우예요. `Device.getPhotos.openPermissionDialog()`로 다시 요청할 수 있어요. |

### 예시 코드

```js
import {
  Device,
  FetchAlbumPhotosPermissionError,
} from "@apps-in-toss/web-framework";

const base64 = true;

async function renderAlbumPhotos() {
  try {
    const photos = await Device.getPhotos({
      base64,
      maxCount: 10,
      maxWidth: 360,
    });

    const container = document.getElementById("photo-list");
    for (const photo of photos) {
      const img = document.createElement("img");
      img.src = base64
        ? "data:image/jpeg;base64," + photo.dataUri
        : photo.dataUri;
      container.appendChild(img);
    }
  } catch (error) {
    if (error instanceof FetchAlbumPhotosPermissionError) {
      console.warn("사진첩 읽기 권한이 없어요.");
      return;
    }
    console.error(error);
  }
}

document
  .getElementById("load-photos")
  .addEventListener("click", renderAlbumPhotos);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers-apps-in-toss.toss.im/documentation/sdk/domains-api/device/device.getphotos.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
