🌟 Summary

Enhanced image resizing and saving mechanism for large images in the YOLOv5 dataset hub.

📊 Key Changes

• Added a fallback using OpenCV for image resizing and saving when the PIL library fails.
• Maintained the functionality for resizing large images to a maximum dimension while reducing the quality for optimized web or app display.
• Exception handling introduced for robustness against PIL-related errors, logging a warning message when necessary.

🎯 Purpose & Impact

• 🎨 Enhanced Compatibility: Provides an alternative library (OpenCV) for image operations, ensuring more consistent behavior across different environments.
• 🔍 Improved Robustness: Helps avoid crashes or failures when processing images due to potential PIL limitations or issues.
• 📉 Reduced Load Times: Resized images will load faster on websites and apps due to their smaller sizes, improving user experience.
• ⚠️ Increased Feedback: Warning messages help in debugging and alert users to any issues encountered during image processing.
