# Download and Save an Image from a URL in Python

This snippet demonstrates how to download an image from a URL and save it locally using Python. This is useful for automating image collection, web scraping, or saving images for processing.

```python
import requests
from pathlib import Path

def download_image(url, save_path):
    """
    Downloads an image from a URL and saves it to the specified path.
    
    Args:
        url (str): URL of the image to download
        save_path (str): Local path where the image should be saved
    """
    try:
        response = requests.get(url, stream=True)
        response.raise_for_status()  # Raise an exception for HTTP errors
        
        # Create parent directories if they don't exist
        Path(save_path).parent.mkdir(parents=True, exist_ok=True)
        
        with open(save_path, 'wb') as file:
            for chunk in response.iter_content(1024):
                file.write(chunk)
        
        print(f"Image successfully saved to {save_path}")
    except requests.exceptions.RequestException as e:
        print(f"Error downloading image: {e}")

# Example usage:
image_url = "https://example.com/image.jpg"
local_path = "images/downloaded_image.jpg"
download_image(image_url, local_path)
```

## Explanation

This code snippet provides a robust solution for downloading images from the internet and saving them locally:

1. **Imports**:
   - `requests` for making HTTP requests (install with `pip install requests`)
   - `pathlib.Path` for handling file paths in a cross-platform way

2. **Functionality**:
   - The `download_image` function takes a URL and local path as input
   - It makes a streaming HTTP GET request to the URL
   - The response is checked for errors
   - Any necessary parent directories are created automatically
   - The image is saved in chunks (memory-efficient for large files)
   - Success/error messages are printed appropriately

3. **Why it's useful**:
   - Handles errors gracefully (invalid URLs, network issues)
   - Works with large files efficiently due to streaming
   - Creates directories automatically if they don't exist
   - Uses modern Python practices (pathlib instead of os.path)

4. **How to use**:
   - Install the required package: `pip install requests`
   - Replace the example URL with a real image URL
   - Specify your desired save path
   - Call the `download_image` function

This snippet is particularly useful for web scraping projects, data collection pipelines, or any application that needs to download and store images programmatically.
