Feature Request: Add Robust Image Download Support to BrowserToolkit

[jmanhype]

🎯 Feature Description

Add robust image downloading capabilities to the BrowserToolkit, allowing agents to directly download and save images from URLs while handling various edge cases and restrictions.

🌟 Current Behavior vs Desired Behavior

Current:

• BrowserToolkit cannot directly download images from URLs, as evidenced by the error message:

  Unfortunately, I don't have the capability to directly fetch raw image data from a URL using the BrowserToolkit
  

• Agents have to suggest manual downloads
• No built-in handling for stock photo sites and protected images
• Limited ability to save and manage downloaded images

Desired:

• Direct image downloading through BrowserToolkit
• Automatic handling of different image sources
• Built-in retry and fallback mechanisms
• Proper error handling and logging
• Support for various image formats and sources

💡 Proposed Solution

Add a new download_image method to BrowserToolkit with the following features:

def download_image(
    self,
    url: str,
    filename: str,
    output_dir: str = "images",
    retry_count: int = 3
) -> Optional[str]:
    """Download an image from a URL with robust error handling."""

Key features:

1. Proper user agent handling
2. Content-type verification
3. Retry mechanism for failed downloads
4. Support for various image formats
5. Automatic directory creation
6. Detailed logging
7. Stock photo site detection and alternative methods

🔍 Implementation Details

1. URL Handling:

   • Support for various URL formats
   • Handle redirects properly
   • Validate URLs before attempting download

2. Error Handling:

   • Handle network timeouts
   • Manage rate limiting
   • Deal with access restrictions
   • Proper exception handling

📋 Example Usage

# Simple usage
path = browser.download_image(
    url="https://example.com/image.jpg",
    filename="dog_with_hat.jpg"
)
