Gemini image generation

What this skill does

# Nano Banana Pro (Gemini 3 Pro Image) Use the bundled script to generate or edit images. Generate ```bash uv run {baseDir}/scripts/generate_image.py --prompt "your image description" --filename "output.png" --resolution 1K ``` Edit (single image) ```bash uv run {baseDir}/scripts/generate_image.py --prompt "edit instructions" --filename "output.png" -i "/path/in.png" --resolution 2K ``` Multi-image composition (up to 14 images) ```bash uv run {baseDir}/scripts/generate_image.py --prompt "combine these into one scene" --filename "output.png" -i img1.png -i img2.png -i img3.png ``` API key - `GEMINI_API_KEY` env var - Or set `skills."nano-banana-pro".apiKey` / `skills."nano-banana-pro".env.GEMINI_API_KEY` in `~/.openclaw/openclaw.json` Specific aspect ratio (optional) ```bash uv run {baseDir}/scripts/generate_image.py --prompt "portrait photo" --filename "output.png" --aspect-ratio 9:16 ``` Notes - Resolutions: `1K` (default), `2K`, `4K`. - Aspect ratios: `1:1`, `2:3`, `3:2`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9`, `21:9`. Without `--aspect-ratio` / `-a`, the model picks freely - use this flag for avatars, profile pics, or consistent batch generation. - Use timestamps in filenames: `yyyy-mm-dd-hh-mm-ss-name.png`. - The script prints a `MEDIA:` line for OpenClaw to auto-attach on supported chat providers. - Do not read the image back; report the saved path only.
