🚀 Google Drive Image Enhancement with Gemini nano banana This workflow automates image enhancement by integrating Google Drive with Google Gemini. It fetches unprocessed images from a source folder, applies AI-driven transformations based on a customizable prompt (e.g., clean and realistic product backgrounds), and uploads the enhanced results into a destination folder—streamlining e-commerce catalog preparation or creative pipelines.

🔑 Key Features

  • Customizable Prompt Node → Easily adjust the style/instructions for Gemini (e.g., backgrounds, lighting, focus).
  • Google Drive Integration → Automatically fetches images from a source folder and uploads results to a target folder.
  • AI Processing via Gemini → Converts original images to Base64, sends them with the prompt to Gemini, and returns enhanced versions.
  • Image Filtering → Processes only files whose mimeType contains "image".
  • Loop Handling → Iterates over all images in the source folder until all are processed.

⚙️ Setup Instructions

  1. Configure Prompt

    • Open the promt node.
    • Replace the text with your desired Gemini instructions (e.g., "Add a clean, realistic background for baby products").

  2. Set Google Drive Folders

    • In origin_folder → set Search Query to the name of the source folder (with unprocessed images).
    • In destination_folder → set Search Query to the name of the target folder (to save results).

  3. Credentials

    • Provide valid Google Drive OAuth2 credentials for both Drive nodes.
    • Provide a Google Gemini API credential for the banana-request node.

  4. Run the Workflow

    • Trigger from the init node.
    • Workflow will download → convert → send to Gemini → reconvert → upload results automatically.

🛠 Customization Guidance

  • Modify the prompt text to change how Gemini processes the images (background, style, product focus).
  • Swap Search Query for folder IDs in Drive nodes if you need more precise targeting.
  • Extend the workflow by chaining post-processing (e.g., watermarking, resizing, or tagging metadata).

Enhance Google Drive Images with Gemini 2.5 Flash AI

This n8n workflow automates the process of enhancing images stored in Google Drive using a Gemini 2.5 Flash AI model. It allows you to select specific images, send them to an AI endpoint for enhancement, and then update the original Google Drive files with the improved versions.

What it does

  1. Manual Trigger: Starts the workflow manually when you click "Execute workflow".
  2. Google Drive - Get All Images: Lists all image files from a specified Google Drive folder.
  3. Filter - Only JPG/PNG: Filters the retrieved files to include only JPG and PNG image formats.
  4. Loop Over Items: Processes each filtered image individually.
  5. Google Drive - Download Image: Downloads the binary data of the current image from Google Drive.
  6. Convert to File - Base64 Encode: Encodes the downloaded image's binary data into a Base64 string.
  7. Edit Fields - Prepare AI Payload: Structures the data for the AI API request, including the Base64 encoded image and other parameters.
  8. HTTP Request - Gemini 2.5 Flash AI: Sends the image data to the Gemini 2.5 Flash AI API for enhancement.
  9. Extract from File - Decode Base64: Decodes the Base64 encoded enhanced image received from the AI API back into binary data.
  10. Google Drive - Update Image: Uploads the newly enhanced image (binary data) back to Google Drive, overwriting the original file.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance (self-hosted or cloud).
  • Google Drive Account: Configured Google Drive credentials in n8n with access to the folder containing the images.
  • Gemini 2.5 Flash AI API Endpoint: Access to an API endpoint for the Gemini 2.5 Flash AI model. This workflow assumes a specific endpoint and payload structure. You will need the API URL and potentially an API key or other authentication details.

Setup/Usage

  1. Import the workflow: Import the provided JSON workflow into your n8n instance.
  2. Configure Google Drive Credentials:
    • Locate the "Google Drive" nodes.
    • Set up your Google Drive credentials if you haven't already. Ensure they have permission to list, download, and update files in the target folder.
    • In the "Google Drive - Get All Images" node, specify the Folder ID where your images are located.
  3. Configure Gemini 2.5 Flash AI API:
    • Locate the "HTTP Request - Gemini 2.5 Flash AI" node.
    • Update the URL field with your Gemini 2.5 Flash AI API endpoint.
    • Configure any necessary Headers (e.g., Authorization with an API key) or Authentication methods required by your AI service.
  4. Activate the workflow: Once configured, activate the workflow.
  5. Execute the workflow: Click "Execute workflow" on the "Manual Trigger" node to start the image enhancement process.

This workflow will iterate through all JPG and PNG images in your specified Google Drive folder, enhance them using the Gemini 2.5 Flash AI, and then update the original files in Google Drive.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
