Image-to-image transformation using n8n and Nano Banana Pro
n8nDemo summary
This clip shows how to upload a personal photo to an n8n workflow and use Nano Banana Pro to transform it into a new scene, such as placing the subject on a beach while maintaining their likeness.
Step-by-step
- Open the n8n form and enter an image prompt describing the desired transformation
- Upload the source image file to the form
- Convert the binary image data into a publicly accessible URL using an HTTP request node
- Add an 'image_input' object to the JSON body of the Nano Banana API request
- Map the public image URL variable to the 'image_input' field
- Execute the workflow and wait for the prediction to process
Watch out for
- Nano Banana requires the input image to be a public URL to view and change it
- The API may return a 422 'unexpected error handling prediction' due to high server load even if the prompt is correct
Tips
- If the workflow fails with a 422 error, try running the exact same image and prompt again as it may just be a temporary server issue
- Check the logs in the 'Key' interface to verify if runs were successful or to see specific error messages
- Use a switch node with different paths to handle potential workflow failures
Highlights
“with this little of a prompt, you'll see how good the results are... this stuff is pretty solid.”
