Send Images to Telegram Groups in Python - Complete Guide

Automate Telegram Group Image Sharing with Python

Need to integrate Telegram group image sharing into your Python applications for data science, automation, or machine learning workflows? This guide shows you how to deliver images to Telegram groups using Python and the WhatsMate Telegram Gateway REST API. Perfect for Python developers building data pipelines, automation scripts, or AI applications that need visual content delivery to group chats.

📋 Prerequisites

Before you begin, ensure you have:

1. A WhatsMate Telegram Gateway account - Required for API access
2. Group membership - The gateway must be a member of the target Telegram group
3. Python 3 installed - Version 3.6 or later recommended
4. Image file ready - Have the image you want to send available locally
5. Requests library - Install via pip install requests

⚠️ Important: The gateway must be a member of the Telegram group you want to send messages to. The group admin phone number is used to uniquely identify the group.

📝 Step-by-Step Implementation

Follow these steps to send your first image to a Telegram group from a Python script:

1. Copy the Python Source Code

Start by copying the following source code into your Python file:

2. Configure a few Parameters

Customize these key parameters in the Python code:

• Line 8: Replace "YOUR_GATEWAY_INSTANCE_ID_HERE" with your Telegram gateway instance ID
• Line 9: Replace "YOUR_OWN_ID_HERE" with your Client ID
• Line 10: Replace "YOUR_OWN_SECRET_HERE" with your Client Secret
• Line 12: Replace 'Muscle Men Club' with the name of your target Telegram group
• Line 13: Replace '19159876123' with the phone number of the group admin (including country code)
• Line 14: Replace "../assets/cute-girl.jpg" with the path to your image file
• Line 15: Replace 'Lovely Girl' with an optional caption for your image

3. Install Required Dependencies

Ensure you have the requests library installed:

pip install requests

Note: The base64 module is included in Python’s standard library, so no additional installation is needed.

4. Make the Script Executable

Set execute permissions on your script:

chmod 755 send-telegram-photo-group.py

5. Run Your Python Script

Execute the script to deliver your image to the Telegram group:

./send-telegram-photo-group.py

Alternative: If the script isn’t executable, run it with Python directly:

python3 send-telegram-photo-group.py

🔧 Common Use Cases

This Python integration is ideal for:

• Data science workflows - Send visualization charts, graphs, or analysis results to Telegram groups
• Machine learning pipelines - Deliver model performance images or training progress updates to teams
• Automation scripts - Integrate with Python automation tools for scheduled image delivery
• Web scraping applications - Send scraped images or screenshots to Telegram groups
• IoT and monitoring systems - Combine with Python-based monitoring tools for visual status updates
