Works in containers	✅ Yes	❌ Often fails
Image generation	✅ Full	✅ Full
Image editing	✅ Yes	✅ Yes
Setup complexity	Just set API key	Install packages first

Bottom line: This skill works anywhere Python 3 exists. No package managers, no virtual environments, no permission issues.

Quick Start

# Generate
python3 /data/clawd/skills/gemini-image-simple/scripts/generate.py "A cat wearing a tiny hat" cat.png

# Edit existing image  
python3 /data/clawd/skills/gemini-image-simple/scripts/generate.py "Make it sunset lighting" edited.png --input original.png

Usage

Generate new image

python3 {baseDir}/scripts/generate.py "your prompt" output.png

Edit existing image

python3 {baseDir}/scripts/generate.py "edit instructions" output.png --input source.png

Supported input formats: PNG, JPG, JPEG, GIF, WEBP

Environment

Set GEMINI_API_KEY environment variable. Get one at https://aistudio.google.com/apikey

How It Works

Uses Nano Banana Pro (nano-banana-pro-preview) - Google's highest quality image generation model:

Pure urllib.request for HTTP (no requests library)
Pure json for parsing (stdlib)
Pure base64 for encoding (stdlib)

That's it. No external packages. Works on any Python 3.10+ installation.

Model

Currently using: nano-banana-pro-preview (also known as Gemini 3 Pro Image)

Other available models (can be changed in generate.py if needed):

gemini-3-pro-image-preview - Same as Nano Banana Pro
imagen-4.0-ultra-generate-001 - Imagen 4.0 Ultra
imagen-4.0-generate-001 - Imagen 4.0
gemini-2.5-flash-image - Gemini 2.5 Flash with image gen

Examples

# Landscape
python3 {baseDir}/scripts/generate.py "Misty mountains at sunrise, photorealistic" mountains.png

# Product shot
python3 {baseDir}/scripts/generate.py "Minimalist product photo of a coffee cup, white background" coffee.png

# Edit: change style
python3 {baseDir}/scripts/generate.py "Convert to watercolor painting style" watercolor.png --input photo.jpg

# Edit: add element
python3 {baseDir}/scripts/generate.py "Add a rainbow in the sky" rainbow.png --input landscape.png
