Issue #30: 🍌 Duncan’s Nano Banana Workflow That’s Too Good To Miss
sell images and videos to clients via OpenRouter inside n8n
Workflow of the Week 🚀
Who Built It: Duncan
What It Does: This workflow lets you generate AI images for free by calling Google’s Gemini 2.5 Flash (aka “Nano Banana”) through OpenRouter and piping the result straight into your stack with n8n. A Chat node captures your prompt, an HTTP request hits the free image endpoint, a Code node cleans the base64, and the final image is uploaded to Google Drive—end-to-end, no paid tokens required (while the free tier lasts). Create a different Google Drive folder for each of your clients and you have a business pumping out content on auto pilot.

Where to Find It: 👉 👉 Get Duncan’s Free AI Image Workflow
Why It’s Incredible: You get a production-ready image generator that actually respects prompts and maintains character consistency—ideal for real estate cards, product shots, thumbnails, and blog visuals. It’s also model-agnostic via OpenRouter, so you can swap providers without rewiring your whole stack.
Key advantages:
$0 image generations (at time of writing) with fast turnaround.
Plugs into any n8n pipeline for SEO, social, or listings at scale.
📊 Difficulty Rating:
🌊🌊 (2/5 — Copy/paste the HTTP request, add a Code node for base64 cleanup, connect Google Drive.)
💰 Get The Bag – Monetize This Workflow
1. 1) Real Estate Listing Packs-on-Demand
Offer agents weekly image packs (exteriors, room angles, staging variants, neighborhood highlight cards) generated from a simple prompt form. Price a setup ($300–$600) plus $149–$399/month for ongoing packs and revisions. Deliver folders per property in Google Drive, ready for MLS and socials. Add captions/hashtags via an LLM to boost distribution.
💡 Pro Tip: Bundle with an auto-post flow (n8n → BLOTATO) for TikTok/IG/YouTube Shorts and charge an extra $99/month.
2) Ecommerce Creative Factory for SMBs
Turn boring catalog shots into themed promo images (seasonal, UGC-style, lifestyle) in bulk. Sell per-SKU packages (e.g., 10 images/SKU at $75) or monthly retainers tied to product drops. Use a Google Sheet as a brief (tone, colors, brand rules), then generate and upload to Drive with consistent naming for Shopify import.
💡 Pro Tip: Add a “brand style lock” prompt library so clients get on-brand creatives every time—an easy $250 add-on.
3) Content Thumbnails & Social Kits
Provide creators a weekly thumbnail kit (3–5 concepts per video) with title overlays and character consistency. Charge $250–$800/month depending on volume and turnaround SLAs. Automate intake via a Typeform → n8n → OpenRouter → Drive loop for frictionless delivery.
💡 Pro Tip: Include an “A/B test pack” (two variants per post) and upsell analytics reporting after 30 days.
BONUS: Turn Free AI Images into UGC Video Ads with RunwayML
You can take the AI images you generate with Duncan’s Nano Banana workflow and instantly repurpose them into scroll-stopping UGC-style videos using RunwayML.
Upload the images into RunwayML Gen-2 (Text-to-Video or Image-to-Video).
Add motion, like a panning effect, zoom, or short looping animations.
Layer in a voiceover (AI or human) and subtitles to make it feel authentic and engaging.
Package it as user-generated content ads for niches like real estate, e-commerce, or SaaS.
👉 Brands are paying $250–$500 per short UGC video. With AI images + RunwayML, you can create these in minutes at no cost.
Monetization angle:
Sell custom UGC-style videos on Fiverr or Upwork.
Offer them as an add-on service to local businesses.
Bundle 5–10 short clips as a package for agencies running paid ads.
