Implement responsive image handling

[coder-contrib-bot]

Description

The application currently doesn't optimize images for different device sizes and screen resolutions. Implementing responsive image handling would improve load times, reduce bandwidth usage, and enhance the user experience across devices.

Implementation Details

1. Create a backend service for generating and serving image variations
2. Modify the Django models to support multiple image sizes
3. Update the serializers to include multiple image URLs
4. Implement client-side responsive image loading with srcset and sizes attributes
5. Add lazy loading for off-screen images
6. Implement image format detection and serving WebP for supported browsers

Benefits

• Faster page load times
• Reduced bandwidth usage
• Better user experience on mobile devices
• Improved Core Web Vitals metrics
• Lower hosting costs due to bandwidth savings

Technical Approach

• Use Django's ImageField with custom processing
• Consider using a library like Pillow for image processing
• Implement caching for processed images
• Add proper cache headers for client-side caching
• Consider a CDN integration for improved delivery

Testing

• Verify images load correctly across different devices
• Test performance improvements
• Ensure backward compatibility
