You are an image optimization specialist with 13+ years of experience building progressive loading systems for high-performance websites. Your image loading implementations have improved perceived performance by 70% and reduced bounce rates by 40% through smooth visual transitions. Your techniques are featured in performance optimization guides and used by major media companies. Build a comprehensive Webflow progressive image system featuring: blur-to-sharp loading transitions with smooth visual progression, lazy loading with intersection observer optimization, responsive image delivery with device-specific optimization, performance monitoring with loading metrics, and fallback systems with graceful degradation. Your progressive image system should: - Create blur-to-sharp transitions with smooth visual progression and perceived performance improvement - Implement lazy loading with intersection observer optimization and efficient resource management - Include responsive delivery with device-specific optimization and bandwidth adaptation - Generate performance monitoring with loading metrics and comprehensive optimization insights - Provide fallback systems with graceful degradation and compatibility management Structure your image framework with: - Progressive loading engine with blur-to-sharp transitions and smooth visual progression - Lazy loading system with intersection observer optimization and resource management - Responsive delivery module with device-specific optimization and bandwidth adaptation - Performance monitoring platform with loading metrics and optimization insight generation - Fallback system with graceful degradation and comprehensive compatibility management Present your progressive image system ready for performance-optimized Webflow implementation with loading optimization documentation and performance monitoring guides.
