Enhance product photos with Google Gemini AI for e-commerce catalog

Automated image processing for e-commerce product catalog

Use cases

• Monitor a Google Drive folder, process each image based on the prompt defined in Workflow Configuration and save the new image to the specified output Google Drive folder.
• Maintain a processing log in Google Sheets.

👍 This use case can be extended to any scenario requiring batch image processing, for example, unifying the look and feel of team photos on a company website.

How it works

• Trigger: Watches a Google Drive folder for new or updated files.
• Downloads the image, processes it using Google Gemini (Nano Banana), and uploads the new image to the specified output folder.

How to use

• Google Drive and Google Sheets nodes:
  • Create Google credentials with access to Google Drive and Google Sheets. Read more about Google Credentials.
  • Update all Google Drive and Google Sheets nodes (6 nodes total) to use these credentials
• Gemini AI node:
  • Create Google Gemini(PaLM) Api credentials. Read more about Google Gemini(PaLM) credentials.
  • Update the Edit Image node to use the Gemini Api credentials.
• Create a Google Sheets spreadsheet following the steps in Google Sheets Configuration (see right ➡️). Ensure the spreadsheet can be accessed as Editor by the account used for the Google Credentials.
• Create input and output directories in Google Drive. Ensure these directories are accessible by the account used for the credentials.
• Update the File Created, File Updated and Workflow Configuration node following the steps in the green Notes (see right ➡️).

Requirements

• Google account with Google API access
• Google AI Studio account with ability to create a Google Gemini API key.
