Generate product mockups with Nano Banana (Gemini 2.5 Flash Image)

This n8n template uses AI to generate product mockups by composing a product image onto a model or template image. This workflow provides a powerful solution for creating dynamic marketing assets and e-commerce visuals. Use cases are many: Instantly create virtual try-on images for apparel, place your product into different scenes for advertisements, or generate custom marketing material without needing a physical photoshoot. Good to know This workflow uses the OpenRouter API to access Google's Gemini model. You will need an OpenRouter account. The model used is google/gemini-2.5-flash-image-preview:free. While this specific model may be free, costs can vary depending on the model you choose and your usage on OpenRouter. Always check their latest pricing. The workflow is triggered by a form. To use it, you must activate the workflow and use its Production URL. How it works A user submits a product image, a template/model image, and a text prompt via the n8n form trigger. The images are then converted to Base64 strings so they can be used in an API request. A multimodal payload is sent to the OpenRouter API. Gemini's image generation model is used, which takes all 3 inputs (the two images and the prompt) to understand how to compose the final image. Gemini generates a new image based on the instructions and returns it as a Base64 string. The workflow extracts this output string and uses a "Convert to file" node to convert the data back into a binary image file, ready for use. How to use First, set up your OpenRouter API credential in n8n. Activate the workflow. Open the Production URL for the form trigger. Upload your product image, your template image, and write a descriptive prompt. Submit the form to execute the workflow and generate your image. Requirements An active n8n instance. An OpenRouter account and API key. Customising this workflow You can easily change the AI model by editing the JSON body in the HTTP Request node. OpenRouter provides access to a wide variety of models from different providers. Add a final step to automatically save the generated image. You can connect nodes for services like Google Drive, AWS S3, or Dropbox after the "Convert to File" node. Replace the Form Trigger with a Webhook Trigger to run this workflow programmatically from another application or service.
