# Nano Banana Pro Image Generation & Editing
Generate new images or edit existing ones using Google's Nano Banana Pro API (Gemini 3 Pro Image).
## Usage
Run the script using absolute path (do NOT cd to skill directory first):
**Generate new image:**
```bash
uv run {baseDir}/scripts/generate_image.py --prompt "your image description" --filename "output-name.png" [--resolution 1K|2K|4K] [--api-key KEY]
```
**Edit existing image:**
```bash
uv run {baseDir}/scripts/generate_image.py --prompt "editing instructions" --filename "output-name.png" --input-image "path/to/input.png" [--resolution 1K|2K|4K] [--api-key KEY]
```
**Important:** Always run from the user's current working directory so images are saved where the user is working.
## Default Workflow (draft > iterate > final)
- Draft (1K): quick feedback loop
- Iterate: adjust prompt in small diffs; keep filename new per run
- Final (4K): only when prompt is locked
## Resolution Options
- **1K** (default) - ~1024px resolution
- **2K** - ~2048px resolution
- **4K** - ~4096px resolution
## API Key
1. `--api-key` argument
2. `GEMINI_API_KEY` environment variable
## Image Editing
Use `--input-image` parameter with the path to the image. The prompt should contain editing instructions.
## Prompt Handling
**For generation:** Pass user's image description as-is to `--prompt`.
**For editing:** Pass editing instructions in `--prompt`.
## Output
- Saves PNG to current directory
- Script outputs the full path to the generated image
- **Do not read the image back** - just inform the user of the saved path
