# Background Images

This directory is where you place your background images for the calendar display.

## Adding Images

1. Copy your image files to this directory:
   ```bash
   cp /path/to/your/images/* static/backgrounds/
   ```

2. Supported formats:
   - JPEG/JPG
   - PNG
   - GIF
   - WebP

3. Recommended image specifications:
   - Resolution: 1920x1080 or higher
   - Aspect ratio: 16:9 (for full-screen displays)
   - File size: Keep under 5MB for faster loading

## Image Rotation

Images automatically rotate at the interval specified in your `.env` file.

To change the rotation interval, edit the `.env` file:

```bash
# Time in seconds (default: 60 seconds = 1 minute)
IMAGE_ROTATION_INTERVAL=60
```

Or directly in `static/js/app.js`:

```javascript
const INTERVALS = {
    BACKGROUND: 60000,  // Milliseconds (60000 = 1 minute)
    ...
};
```

## Tips

- Use high-quality images for best display
- The app will randomly select images from this directory
- Delete or move images you no longer want displayed
- Images are cached by the browser, so you may need to hard-refresh (Ctrl+F5) to see new images immediately
