🚀 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

Configure Prompt
- Open the promt node.
- Replace the text with your desired Gemini instructions (e.g., "Add a clean, realistic background for baby products").
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).
Credentials
- Provide valid Google Drive OAuth2 credentials for both Drive nodes.
- Provide a Google Gemini API credential for the banana-request node.
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).
