Video: Easy Image Combiner with Nano Banana and n8n

Another example of using a form to combine multiple images with Nano Banana and n8n.

As I mentioned in another post, using multiple image binaries in n8n is not the easiest thing to do.

In this workflow I went for a more direct route and "hardcoded" a 3 image path so this workflow will expect 3 images to transform into 1. You could also just delete the 3rd if you only want to combine 2 images.

Very similar to the Nano Banana workflow though, but this does also need to build out a more dynamic image payload to send into the Gemini 2.5 Flash Image API.

Sample JSON for inlineData object for images:

{

"inlineData":{

"mimeType":"{{ $json.mimeType }}",

"data":"{{ $json.data }}"

}

Sample Gemini 2.5 Flash Image request body:

{

"contents": [

{

"parts": [
