Nano Banana — Image Generation

Generate and edit images via the Gemini API. If the API key is missing, run /nano-banana:setup.

Workflow

Determine the mode from the user's request:
- Creating a new image from text? → Text-to-image (no --images)
- Editing/retouching an existing image? → Image editing (--images source.png)
- Applying one image's style to another? → Style transfer (--images style.png target.png)
- Combining or referencing multiple images? → Multi-image (--images a.png b.png ..., up to 14)
- Need 2K or 4K output? → Add --resolution 2K|4K to any mode above
Craft the prompt — describe the desired result narratively. See references/prompting-guide.md for domain-specific patterns (website visuals, placeholders, product shots, etc.).
Run the script:

python "$CLAUDE_PLUGIN_ROOT/scripts/genimage.py" --prompt "..." [options]

Show the result — read the output image and present it to the user.

Flags

Flag	Required	Purpose
`--prompt "text"`	Yes	Describe the desired image
`--output file.png`	No	Output path (default: `generated_image.png`)
`--images path [...]`	No	Input image(s) — omit for text-to-image
`--aspect-ratio RATIO`	No	`1:1` `2:3` `3:2` `3:4` `4:3` `4:5` `5:4` `9:16` `16:9` `21:9`
`--resolution RES`	No	`1K` `2K` `4K` (uppercase K required, triggers Pro model)

Models

Nano Banana 2 (gemini-3.1-flash-image-preview): Default. Fast, high-quality.
Nano Banana Pro (gemini-3-pro-image-preview): Auto-selected when --resolution is set. 4K output, advanced reasoning, high-fidelity text rendering.

Common Use Cases → Flags

Use case	Example command
Website hero image	`--prompt "..." --aspect-ratio 16:9`
Social media post	`--prompt "..." --aspect-ratio 1:1`
Mobile banner	`--prompt "..." --aspect-ratio 9:16`
Placeholder / mockup	`--prompt "..." --output placeholder.png`
Edit existing photo	`--prompt "remove the background" --images photo.png`
Style transfer	`--prompt "Apply watercolor style" --images style.png photo.png`
High-res asset	`--prompt "..." --resolution 4K`

Editing

All editing is text-guided — describe what to change ("replace the sky", "remove the person", "add a sunset") and Gemini identifies and modifies regions automatically. No masks needed.
