# 1. WORKING WITH THE PHOTO LIBRARY
The app helps you quickly and efficiently organize your photo library. You can easily select your best shots by adding them to Favorites and delete unsuccessful ones.
Key Features:
## 1. Flags and Tags Management
Assign flags, ratings, and color tags to photos for convenient sorting:
* Green flag: For successful shots
* Red flag: For unsuccessful shots
Photos are automatically sorted into albums based on the assigned flags, ratings, or color tags.
***
## 2. Export and File Management
When you tap the export button, the app will offer the following options:
* Add all photos with a green flag to the Favorites album
* Move photos with a red flag to the Trash
By default, photos remain in the Trash for 30 days, but they can be manually deleted earlier.
***
## 3. Photo Viewing and Comparison
Quickly switch between photos by tapping the screen edges. This feature is available even in zoom mode, allowing you to compare details and assess the sharpness of multiple shots.
## 4. Gesture Control
Use swipe gestures for easy flag management:
* Swipe up: Sets the green flag
* Swipe down: Sets the red flag
Through the settings menu, you can enable Auto-Advance mode, which automatically moves to the next photo after setting a flag, speeding up the sorting process.

## 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://photopicker.gitbook.io/v3/photo_library.md?ask=&goal=
```
`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.
