Quick overview

This workflow manually processes car photos from Google Drive, sends each image plus a studio backdrop and logo to the Google Gemini Image API for background replacement and license-plate branding, and uploads the generated studio-style images back to an output Google Drive folder.

How it works

  1. Runs when you manually execute the workflow.
  2. Lists all image files in a specified Google Drive input folder and processes them one at a time.
  3. Downloads the current car photo and also lists and downloads the studio asset images (virtual backdrop and logo) from a separate Google Drive folder.
  4. Builds a multimodal request that instructs Google Gemini to classify the shot (exterior vs interior/engine), replace the background accordingly, and swap any visible license plate with the provided logo.
  5. Sends the request to the Google Gemini image generation endpoint and receives a generated image in the response.
  6. Extracts the generated image, names it using the original filename with a “_studio.jpg” suffix, and uploads it to a specified Google Drive output folder.

Setup

  1. Add Google Drive OAuth2 credentials and set the input, studio assets, and output folder IDs in the Google Drive nodes’ queries/parent folder settings.
  2. Add a Google Gemini API key as an n8n HTTP Header Auth credential (x-goog-api-key) and select it in the HTTP Request step.
  3. Ensure the studio assets folder contains the reference images named exactly "virtual_studio.png" and "logo.png" so they are correctly picked up for compositing and plate replacement.

Requirements

  • Google Drive account (OAuth2) with an Input, Studio Assets, and Output folder created
  • Google Gemini API key with access to the gemini-2.5-flash-image model
  • A studio backdrop image and a logo image, saved exactly as virtual_studio.png and logo.png

Customization

  • Swap the Manual Trigger for a Schedule Trigger or a Drive "File Created" trigger to run fully automated as new photos land
  • Add a separate backdrop for interior/engine shots instead of a single shared studio reference, for more tailored compositing
  • Add a Slack or email notification node after the upload step to alert the team when a batch finishes
  • Extend the Gemini prompt to auto-crop output to a fixed aspect ratio matching your listing platform's requirements

Additional info

This workflow replicates the core function of commercial "virtual photo studio" tools entirely inside n8n using Google's Gemini 2.5 Flash Image model — at a fraction of the cost and with full control over the pipeline.
