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! 🍌

With Nano Banana now available on Openrouter, it makes even easier to create a quick workflow that can edit images on the fly. This time I dive a little deeper into the text-to-edit capabilities of Nano Banana, showing how easily it create something that you'd spend a few minutes editing in Canva, dragging in assets, moving font, changing colors, adding shadows. Instead this flow can generate it for you in one command, and be easily modified to create variations on the fly on a schedule. It uses an HTTP Request node to call Openrouter so the url is below and the JSON body and full workflow are also attached. Let me know if you have any questions or what else you'd like to see!
