Gallery-dl ComfyUI Node - Complete Setup Guide

Overview

This is a comprehensive ComfyUI node for downloading images and media from various websites using gallery-dl. The node includes support for authentication, file organization, and robust error handling.

✅ Completed Features

Core Features

  • URL Support: Download from URL lists or URL files
  • Authentication: Browser cookies and exported cookie files
  • File Organization: Automatically sort files into subfolders by type
  • Download Archive: Avoid re-downloading the same files
  • Video Filtering: Option to skip video files
  • Metadata Extraction: Save download information to JSON
  • Debug Output: Comprehensive status and error reporting

File Organization

Downloaded files are automatically sorted into subfolders by type, WITHIN each profile directory:

Example for Instagram profile:

gallery-dl-output/
├── instagram/
│   └── janaioannaa/
│       ├── images/     ← Photos and images (jpg, png, webp, etc.)
│       ├── videos/     ← Video files (mp4, webm, mkv, etc.)
│       ├── audio/      ← Audio files (mp3, flac, wav, etc.)
│       └── other/      ← Documents and other files (pdf, txt, etc.)
└── gallery-dl-metadata.json

Key Features:

  • Files are organized WITHIN each profile/site directory
  • Preserves gallery-dl's original directory structure
  • Each profile gets its own organized subdirectories
  • No files are moved to the root level

🎯 Optimal Setup by Platform

Instagram (Best Practice)

✅ config_path: LEAVE EMPTY (not needed)
✅ cookie_file: './configs/instagram_cookies.json'
✅ use_browser_cookies: False
✅ organize_files: True
✅ use_download_archive: True

Why this works:

  • Instagram only needs cookies for authentication
  • No config file required
  • Exported cookies are more reliable than browser cookies
  • Files get organized automatically

Reddit (Best Practice)

✅ config_path: './configs/gallery-dl-no-reddit.conf'
✅ cookie_file: LEAVE EMPTY
✅ use_browser_cookies: True
✅ organize_files: True
✅ use_download_archive: True

Why this works:

  • Reddit API credentials are problematic due to 2FA
  • Browser cookies work better for Reddit
  • Config file can disable Reddit if needed
  • Files get organized automatically

General Sites (Twitter, Imgur, etc.)

✅ config_path: LEAVE EMPTY (unless site-specific config needed)
✅ cookie_file: LEAVE EMPTY
✅ use_browser_cookies: True
✅ organize_files: True
✅ use_download_archive: True

🔍 Debug Information

The node provides comprehensive debug output including:

  • Cookie file conversion status
  • Authentication attempts
  • File organization results
  • Download progress
  • Error messages and warnings

🧪 Testing

Run the test scripts to verify functionality:

# Test file organization
python Docs/test_file_sorting.py

# Test Instagram setup
python Docs/test_instagram_optimal_setup.py

🛠️ Troubleshooting

Common Issues

  1. "gallery-dl not found"

    • Install gallery-dl: pip install gallery-dl

  2. Authentication fails

    • For Instagram: Use exported cookie file
    • For Reddit: Use browser cookies, avoid API credentials

  3. Files not organizing

    • Ensure organize_files: True
    • Check debug output for move operations

  4. Downloads are slow

    • Node includes automatic rate limiting (1 second between requests)
    • This is intentional to be respectful to servers

  5. Browser cookies not working

    • Try Firefox (works without admin privileges)
    • For Chrome/Edge, run ComfyUI as administrator

Debug Steps

  1. Check the debug output in the node's summary
  2. Verify file paths are correct
  3. Test authentication with a single URL first
  4. Check if gallery-dl works from command line
