Nano Banana AI Image Generator

This workflow automates advanced AI image generation using Google Gemini 2.0 Flash, replacing manual image editing with a production-ready pipeline. It processes reference images and text prompts from direct uploads or Airtable, optimizes prompts, generates enhanced images, uploads results to ImgBB, and updates Airtable records, saving hours per project. Graphic designers or content creators producing 10+ images monthly benefit most. The Webhook node handles inputs, a Code node validates and fetches Airtable data, another integrates with Gemini for multimodal generation, a third uploads images and updates Airtable, and the Respond to Webhook node formats responses, streamlining image production. The workflow saves ~5 hours weekly by automating 10+ image generations. Ideal for small design teams or freelancers, it requires n8n, Google Gemini API (~$0.02/1k tokens), Airtable (~$10/month base tier), and optional ImgBB (~$4/month). Scalability is limited by API rate limits; moderate technical skills are needed. Install n8n from n8n.io or use cloud.n8n.io. Obtain Gemini API key from Google Cloud, Airtable API key from airtable.com, and ImgBB API key from imgbb.com. Configure the Webhook node with a URL like https://your-n8n-instance/webhook/nano-banana-advanced and header authentication. Update Airtable node URLs with your base and table IDs. Test with payloads like { \"imageBase64\": \"data:image/jpeg;base64,...\", \"textPrompt\": \"Enhance this logo\" } or { \"recordId\": \"rec123\" } via Postman. Activate in n8n. Monitor for errors like invalid base64 or API failures in logs. Optimize by batching requests and rotating API keys quarterly for security.", "businessValue": "Saves 5 hours/week automating 10+ AI image generations", "setupTime": "45-60 minutes", "difficulty": "Intermediate", "requirements": [ "n8n (free/community or cloud), Google Gemini API, Airtable, optional ImgBB", "API keys for Gemini, Airtable, and ImgBB", "Stable internet, modern browser, moderate coding for setup" ], "useCase": "Automating AI-enhanced image generation for design or content creation"
