Image editing with reference

bash
python ~/.claude/skills/nano-banana-pro/generate_image.py "add a rainbow in the sky" --reference landscape.png

Output

Images are saved with timestamp filenames:

  • •Format: {timestamp}_{sanitized_prompt}.{format}
  • •Example: 20260106_143052_serene_mountain_landscape.png

The script outputs the full path to the generated image.

Requirements

  • •Python 3.10+
  • •google-genai library
  • •GEMINI_API_KEY environment variable

Notes

  • •Gemini 3 Pro Image requires paid billing (no free tier)
  • •Generated images include SynthID watermarking
  • •Reference images enable style transfer and editing capabilities
  • •No text by default: The script automatically adds "no text/typography" instructions unless your prompt explicitly mentions text, typography, words, or labels. To include text, add words like "with text overlay" or "include typography" to your prompt.
