Nano Banana Image Combiner

When should I use Nano Banana to combine images?

Use this workflow when several reference images need to inform one new composition: for example, a subject, environment, palette, and styling direction. Nano Banana accepts image URLs and a prompt through its editing API; Story321 currently presents a 2–10 image upload workflow with aspect-ratio controls.

Nano Banana multi-image workflow on Story321

• Multiple visual references

  Upload 2–10 images in the current Story321 form to guide one combined composition.

• Natural-language direction

  Use a written prompt to explain which subjects, placements, mood, and visual details matter most.

• Composition framing

  Choose Auto or an available aspect-ratio preset to steer the shape of the generated result.

• Reference-aware exploration

  Use several images to establish a visual direction, then inspect the complete generated image before relying on it.

How to combine images with Nano Banana

1. 1

   Choose your references

   Upload 2–10 images you have permission to use. Give each image a distinct role in the intended composition.

2. 2

   Set the frame

   Select Auto for a reference-led frame or choose an aspect ratio for the format you plan to test.

3. 3

   Describe the composition

   State how the references should relate, then name the details that should remain visually important.

4. 4

   Review and iterate

   Check the complete image for unintended changes and revise a single instruction before trying another generation.

Nano Banana image-combining notes

• Story321's 2–10 image input range is a product-interface limit; it is not presented as an official Google model limit.
• The result is generative: it can alter visual details, including text, faces, logos, lighting, scale, and object relationships.
• Google states that images created or edited with Gemini 2.5 Flash Image include an invisible SynthID digital watermark.
• Use only images you have permission to upload and confirm the live form's credits and controls before generating.
