Nanobanana ignores source image and generates a new one from scratch

Hello! :waving_hand:

I’m asking for help because I can’t find any solution.

If there’s already a topic about this, please let me know.

I’m trying to create an automated workflow that modifies an image with Nanobanana whenever an image is dropped into a target folder.

From the logs, everything looks fine, but the node that generates the image doesn’t seem to use the image I dropped. Instead, it generates an image from scratch without using the latest image in the folder.

The URL I’m using is:

Could anyone help me figure out what I’m doing wrong?

Thanks a lot!

Hey @Asuke! The issue you’re running into is that your workflow isn’t actually passing the dropped image as a reference image to Generate image node. Right now, it’s only sending the file name in the prompt, so the model has nothing to base the generation on — which is why it keeps creating a brand-new image from scratch.

To fix this:

  1. Open your Generate Image node.

  2. Click Show More to reveal additional options.

  3. Enable Reference Image.

  4. Pass the uploaded file into that Reference Image field instead of the prompt.

Once that’s connected your workflow should run as expected.

Example workflow for reference: Gumloop | Automation Builder
