Build an Image Generation Bot With Nano Banana Pro

Google just released Gemini 3 and with it their new image model Nano Banana Pro. The results are crazy realistic and the price is surprisingly low. So I built a full image generation system in n8n that lets you create images through a simple chat interface.

The bot can generate three types of images. You can create an image from text. You can use an existing image as a reference. Or you can upload multiple images and combine them into a brand new one.

I walk through how the whole system works:

1. How to connect Nano Banana Pro through Kie.ai using HTTP requests

2. How to build a clean n8n form that collects prompts and file uploads

3. How to enhance prompts with AI before sending them to the model

4. How to use Google Drive as a free image host for the uploaded files

5. How to handle the async generation loop until the image is done

6. How to send the final image back through a Telegram chat

The bot can make infographics, edits, memes or realistic image composites. And you can run the whole thing from your phone.
