This system automatically updates images based on a schedule and content bank in Google Sheets. It uses GPT-5-mini to select the best image template based on the content and then uses Nano Banana to replace the template image with content from the Google Sheet. This runs of a schedule trigger but it could easily be replaced with a Telegram bot to handle the input instead. Requirements: Google Client for Google Sheets and Google Drive Openrouter.ai account for Nano Banana You can create template images by going to Nano Banana directly at https://aistudio.google.com/ The full workflow is attached below. Let me know if you have any questions!

With just a few nodes in n8n you can have a simple image editor using Google's Gemini 2.5 Flash Image model, codenamed "Nano Banana". I'm using an HTTP Request node to call the Gemini API directly, basically following the same process from https://aistudio.google.com/apikey, and with a n8n and a little base64 encoding and decoding, you've got a prompt-based image editor. Here is the JSON body example of the Gemini request for reference: `{ "contents": [ { "parts": [ { "text": "{{ $('On form submission').item.json.Prompt }}" }, { "inlineData": { "mimeType": "image/png", "data": "{{ $json.data }}" } } ] } ], "generationConfig": { "responseModalities": ["IMAGE"] } }` This was one of those immediately powerful workflows. I actually ended up using it create the thumbnail to remove the Salesforce branding from my sweatshirt after the fact. Really powerful model and really easy setup. May have to do a few more workflows using Nano Banana. Let me know if you try it out or have any other ideas you want to see! 🍌
