Build a bulk image downloader

To build a bulk image downloader, you can create a simple script in Python using libraries like requests, os, and BeautifulSoup for HTML parsing. Below is a complete working script that downloads all image files (.jpg, .jpeg, .png, .gif, etc.) from a given web page URL.

✅ Python Script: Bulk Image Downloader

python
CopyEdit
import os
import requests
from bs4 import BeautifulSoup
from urllib.parse import urljoin

# Set the URL of the webpage to scrape
url = input("Enter the webpage URL: ").strip()

# Create a folder to store downloaded images
output_folder = "downloaded_images"
if not os.path.exists(output_folder):
    os.makedirs(output_folder)

# Headers to simulate a browser visit
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)"
}

try:
    response = requests.get(url, headers=headers)
    response.raise_for_status()

    soup = BeautifulSoup(response.text, "html.parser")
    images = soup.find_all("img")

    count = 0
    for img in images:
        img_url = img.get("src")
        if not img_url:
            continue

        # Join relative URLs with base URL
        full_url = urljoin(url, img_url)

        # Get the image content
        img_data = requests.get(full_url, headers=headers).content
        img_name = os.path.join(output_folder, f"image_{count}.jpg")

        # Save the image
        with open(img_name, "wb") as f:
            f.write(img_data)
        print(f"Downloaded: {img_name}")
        count += 1

    print(f"nTotal images downloaded: {count}")

except requests.RequestException as e:
    print(f"Error: {e}")

💡 Features

• Downloads all images from any public webpage.

• Saves images in a folder named downloaded_images.

• Automatically resolves relative image URLs.

• Uses a user-agent to mimic browser behavior.

📦 Requirements

Install dependencies using pip:

bash
CopyEdit
pip install requests beautifulsoup4

🔧 Optional Enhancements

• Add file extension detection from Content-Type.

• Filter by image size or resolution.

• Add retry mechanism or timeout handling.

• Download from a list of URLs (batch mode).

• GUI with tkinter or PyQt for user interaction.

Let me know if you want it turned into a GUI app, CLI tool with options, or browser extension.
