Bulk Image Downloader: Fast Methods to Save Entire Galleries

How to Use Bulk Image Downloader for Efficient Image CollectionEfficiently collecting large numbers of images from websites can save hours compared to manual saving. Bulk Image Downloader (BID) is a popular tool designed to automate that work. This guide explains how to use BID effectively and responsibly, from installation and basic usage to advanced techniques and troubleshooting.

What Bulk Image Downloader does

Bulk Image Downloader automates finding and downloading images from web pages, image galleries, and some hosted services. It parses page HTML and embedded links to assemble a list of full-resolution image URLs and then downloads them in batches, skipping duplicates and allowing filename templates, filters, and resume support.

Installing and preparing BID

1. System requirements:

   • Windows is the primary platform; BID integrates with common browsers via an extension.
   • A reliable internet connection and sufficient disk space for image storage.

2. Acquire BID:

   • Download BID from its official site or an authorized reseller. Choose the latest stable version.
   • Install following on-screen prompts. Grant permissions for browser integration if you want one-click capture from pages.

3. Browser integration:

   • Install the BID browser extension (available for major browsers). The extension adds a context-menu option and allows capturing galleries directly from the page you’re viewing.
   • If your browser blocks the extension, enable it in browser settings and restart.

Basic workflow: capture, parse, download

1. Capture a page or gallery:

   • Open the page with the images. Use the BID browser button or context menu (“Download images with Bulk Image Downloader”) to send the page to BID.
   • Alternatively, copy a page URL and paste it into BID’s URL field.

2. Parsing:

   • BID will scan the page for image links, embedded media, and gallery pages. It tries to find the highest-resolution image files rather than thumbnails.
   • Review the list of discovered images. Use the built-in preview to verify image content and resolution.

3. Select and filter:

   • Uncheck images you don’t want.
   • Use filters to exclude by file type (e.g., skip .gif) or by size (minimum dimensions or file size) to avoid thumbnails and icons.

4. Set destination and naming:

   • Choose a download folder. Create separate folders per site or per task to stay organized.
   • Use filename templates (BID supports variables like page title, sequence number, original filename) to create consistent, sortable names.

5. Download:

   • Start the download. BID supports multi-threaded downloading for speed and will skip duplicates.
   • Monitor progress and pause/resume as needed.

Advanced techniques

• Recursive gallery crawling:

  • Some websites spread galleries across multiple pages. Enable recursive crawling to follow gallery links and collect images from all pages. Set a sensible depth to avoid crawling the whole site.

• Authentication and private galleries:

  • For password-protected or members-only areas, sign into the site in your browser before capturing the page, so BID’s extension captures the authenticated session. Alternatively, configure cookies or use a supplied cookie file if BID supports it.

• Custom URL filters and regex:

  • Use regular expressions or URL patterns to include/exclude image URLs. This is useful when pages contain ads, tracking images, or unrelated media.

• Bandwidth and rate limiting:

  • To avoid server overload or being blocked, set a maximum number of simultaneous connections and add delays between requests. Respect site terms of service and robots.txt where applicable.

• Integration with image organizers:

  • After download, import images into your preferred DAM or image manager (Adobe Lightroom, XnView, etc.). Use BID’s filename templates to embed metadata like source or capture date to make cataloging easier.

Legal and ethical considerations

• Copyright: Downloading images for personal offline viewing is different from redistribution or commercial use. Always confirm image licensing and copyright before using images beyond personal use.
• Terms of service: Some sites prohibit automated scraping. Check and respect the site’s terms of service.
• Rate limits and server load: Use polite crawl settings to avoid harming site performance.

Troubleshooting common problems

• Few or no images found:
  • The site may use dynamically loaded images via JavaScript or obfuscation. Try using the browser extension on the open page (so the page has fully loaded) or enable JavaScript rendering options if BID offers them.
• Downloads fail or are blocked:
  • Check for anti-bot measures (CAPTCHAs, rate limits). Slow down requests, add delays, or use authenticated sessions.
• Wrong image sizes (thumbnails only):
  • Look for URLs that include size parameters and try editing them (remove size tokens) or enable BID’s option to find full-size image URLs.
• Duplicate filenames:
  • Use filename templates with sequence numbers or folder-per-source to avoid overwriting.

Example step-by-step: downloading an album

1. Open the album page in your browser and ensure all images are visible (click any “load more” buttons).
2. Click the BID browser button to send the page.
3. In BID, inspect the parsed list; enable only images matching your desired resolution.
4. Set folder: Images/PhotographerName/AlbumTitle.
5. Set filename template: {albumtitle}{num}_{orig_filename}.
6. Set maximum 4 concurrent downloads and a 500 ms delay.
7. Click Download and wait for completion. Import into your image manager afterwards.

Alternatives and when to use them

• If you need cross-platform support (macOS or Linux), consider alternatives that support those OSes or run BID under Wine/compatibility layers.
• For complex site automation or scheduled scraping, use scripts (Python + requests/BeautifulSoup or Selenium) where you can customize behavior extensively.

Final tips

• Test settings on a small gallery first to confirm filters and naming work as expected.
• Keep backups and track sources, especially when collecting for research or professional use.
• Regularly update BID and its browser extension for compatibility and security fixes.
