n8n: Combine multiple images into one generation
n8nDemo summary
The video shows how to pass multiple base64 encoded images into a single API call to blend elements, such as placing a specific hat from one image onto a character from another.
Step-by-step
- Add multiple file upload elements to your form for the base images
- Add a separate 'Extract from File' node for each uploaded image
- Set unique output field names for each conversion node to prevent data overwriting
- Open the image generation node and expand the request body
- Copy the object containing the inline data for the first image
- Add a comma and paste the object to include the base64 content for the second image
- Run the workflow to generate the combined image
Options
- Upload up to 12 images to Nano Banana Pro
Watch out for
- You must use different names for the output fields in the conversion nodes or the values will overwrite each other
Tips
- Test each conversion step individually to ensure the images are being received correctly
- Use specific prompts to describe how the images should be blended, such as 'Sitting Sweeney wears the pink hat'
