Edit ad image variations with Nano Banana and n8n

Dynamic Image Variation Prompt

Ad Image Variation Automation Workflow

1. Set up an Airtable Base with a column for the original image (Attachment) and a text column for object replacement instructions.
2. Upload the original ad image (e.g., a photo of Tacos) into the Airtable Attachment field.
3. Configure the n8n 'Airtable Trigger' or 'Button' node to start the workflow whenever a record is updated.
4. Add an 'HTTP Request' node or an Airtable connection node to download the image file into the n8n workflow.
5. Connect to the Gemini node (Select model: Nano Banana / Gemini 2.5 Flash).
6. In the Gemini node configuration, map the downloaded image data to the visual input section.
7. Enter a dynamic prompt into the Gemini node that combines the original image with the object replacement instructions (e.g., change Tacos to Chicken Wings).
8. Run the workflow to generate the new image variations.
9. Use the 'Google Drive' node to upload the resulting image variations to cloud storage.
10. Update the original spreadsheet or Airtable record with the newly generated image links.
