|---|
| Dependencies | None (stdlib only) | google-genai, pillow, etc. |
| Requires pip/uv | ❌ No | ✅ Yes |
| Works on Fly.io free | ✅ Yes | ❌ Fails |
| 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 Proimagen-4.0-ultra-generate-001 - Imagen 4.0 Ultraimagen-4.0-generate-001 - Imagen 4.0gemini-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
