Telegram Image Downloader

Python script to sync images in a Telegram chat with a local folder (one-way download).

How to

1. Register new api id and hash at https://my.telegram.org

2. Run the following command to build the docker container

docker build -t telegram-image-downloader .

3. Set Credentials in file ./credentials.env (file is ignored via .gitignore)

TELEGRAM_API_ID=<API_ID>
TELEGRAM_API_HASH=<API_HASH>
TELEGRAM_PHONE=<PHONE_NUMBER>
TELEGRAM_DOWNLOAD_FOLDER=<DOWNLOAD_FOLDER_PATH>
TELEGRAM_CHATS=<CHAT_LIST> # comma separated list of chat names

4. Source the file

source credentials.env

5. Start downloading:

docker run -v $(pwd)/contents:/contents -it telegram-image-downloader /bin/bash -c "python /contents/download.py $TELEGRAM_API_ID $TELEGRAM_API_HASH $TELEGRAM_PHONE_NUMBER $TELEGRAM_DOWNLOAD_FOLDER \"$TELEGRAM_CHATS\""

You will be prompted to enter the PIN you received in telegram (another device/app) and password (if enabled). After that the download starts.
