The latest version is a major upgrade with 25+ new features including: Advanced Directory Management, Flat Structure with Hashed Filenames (perfect for large archives), Interactive Folder Tree interface, Performance Caching System, Rate Limiting, Modern Joomla Compatibility (4.x and 5.x), Cross-Platform Support, Enhanced Logging, and 85% faster admin interface. It's designed for enterprise-scale websites and large image archives.

2. What are the system requirements?

The plugin supports modern Joomla versions (4.x and 5.x) with universal compatibility. It works on Windows and Linux servers, shared hosting, VPS, dedicated servers, and cloud environments. The robust system ensures it works regardless of your hosting configuration.

3. Is the plugin suitable for large websites?

Absolutely! The plugin is specifically designed for large-scale operations. The Flat Structure and Hashed Filenames features are perfect for sites with extensive image archives and deep folder structures. The lazy-loading interface prevents browser freezing even with thousands of folders.

New Features Questions

4. What is the Flat Structure feature and when should I use it?

Flat Structure stores ALL WebP files in a single directory without subdirectories, regardless of where the original images are located. This is ideal for:

• Large news websites with deep folder structures
• Sites with extensive archived images
• Multi-author sites with complex organization
• Archives where WebP files are purely for performance (not organization)

Benefits: Easier cleanup, no deep directory performance issues, simplified maintenance.

5. What are Hashed Filenames and why would I need them?

Hashed Filenames generate unique MD5-based names for WebP files instead of using the original filename. This prevents conflicts when multiple images have the same name in different folders. Perfect for large archives and multi-author sites. The plugin maintains a JSON mapping file for reverse lookup.

6. How does the new Caching System work?

The caching system stores conversion results and statistics in JSON files, reducing processing overhead by up to 90% for repeat operations. Cache lifetime is configurable (1-168 hours). This dramatically improves performance for sites that frequently regenerate or check image conversions.

7. What is the Interactive Folder Tree?

The new interface displays your image directory structure as an expandable tree with checkboxes. You can select one, multiple, all, or none folders for processing. It uses lazy loading to handle thousands of folders without freezing your browser, loading maximum 50 folders per request.

Performance and Compatibility

8. Will the plugin work on my existing Joomla installation?

Yes! The plugin is designed for modern Joomla installations (4.x and 5.x) with robust compatibility features. It automatically detects your Media component settings and adapts accordingly, ensuring seamless operation across different configurations.

9. I have a Windows server. Will this work?

Yes! The plugin includes cross-platform path normalization that handles Windows backslashes and Linux forward slashes automatically. It's been specifically tested and optimized for Windows Server environments.

10. How much faster is the new admin interface?

The admin interface is 85% faster due to lazy loading, optimized queries, and smart folder scanning. What used to take 10-20 seconds now loads in 2-3 seconds. Memory usage is reduced by 60% through enhanced memory management.

Configuration and Setup

11. How do I configure the plugin for a large news website?

For large news sites with extensive archives:

• WebP Output Directory: "webp_thumbs"
• Use Flat Structure: Yes
• Use Hashed Filenames: Yes
• Quality: 75%
• Enable Cache: Yes (48-72 hours)
• File Size Limits: 5KB - 15MB

This creates a single "webp_thumbs" folder with all WebP files using unique hashed names.

12. What's the difference between maintaining directory structure and flat structure?

Maintaining directory structure mirrors your original folder organization in the WebP output directory. Flat structure puts ALL WebP files in one directory regardless of original location. Choose based on your needs:

• Maintain structure: Better for organized sites, photographers, agencies
• Flat structure: Better for large archives, news sites, performance optimization

13. How do I migrate from the old version to the latest version?

Migration is seamless! The plugin maintains full backward compatibility:

• All existing WebP files continue working
• Previous settings are preserved
• No configuration changes required
• New features are available immediately

Simply update the plugin and optionally configure new features.

Troubleshooting New Features

14. The folder tree is loading slowly. What can I do?

The lazy loading system is designed to handle this, but for extremely large directory structures:

• The system automatically limits to 50 folders per load
• Initial scan depth is limited to 2 levels
• Use the "Load more" functionality for deeper levels
• Consider using Flat Structure for better performance

15. I'm getting rate limiting messages. What does this mean?

The plugin includes built-in abuse prevention with these limits:

• Batch operations: 5 per hour
• Single conversions: 50 per hour
• Delete operations: 10 per hour
• List operations: 100 per hour

Super administrators bypass these limits. For legitimate heavy usage, wait for the time window to reset.

16. How do I clean up hashed WebP files?

The plugin includes automatic cleanup tools:

• Orphaned File Detection: Automatically removes WebP files when originals are deleted
• Mapping Cleanup: Cleans the JSON mapping file of invalid entries
• Directory Management: Use the cleanup tools in the admin interface
• Manual Cleanup: Use "Delete Generated WebP Images" to remove all WebP files

Advanced Usage

17. Can I use different settings for different types of images?

Yes! Use the exclusion settings strategically:

• Exclude specific folders from automatic conversion
• Use the folder tree to select specific folders for batch conversion with different quality settings
• Process logos and important images separately with higher quality
• Use file size filtering to handle different image types appropriately

18. How does the plugin handle my custom Media component configuration?

The plugin automatically detects your Media component settings and generates correct URLs. Whether you use "images", "media", "assets/images", or any custom path, the plugin adapts automatically. This fixes the "corrupted image" issue that occurred with custom media paths.

19. Is the plugin suitable for shared hosting?

Absolutely! The plugin is optimized for shared hosting with:

• Conservative memory usage settings
• Configurable memory thresholds
• Rate limiting to prevent resource abuse
• Efficient processing algorithms
• Graceful degradation if resources are limited
