 **What Changed:**
-- Enabled Next.js automatic image optimization in `next.config.mjs`
-- Added support for modern formats (AVIF, WebP)
-- Configured responsive device sizes and image sizes
-- Set up remote pattern matching for external images
+- Used native `<img>` tags with `loading="lazy"` attribute
+- Native browser lazy loading for below-the-fold images
+- Kept `images.unoptimized: true` in `next.config.mjs`
+- Background images for hero section (CSS-based)
 
 **Benefits:**
-- Automatic format conversion to WebP/AVIF (up to 50% smaller file size)
-- Lazy loading by default for off-screen images
-- Responsive images with srcset generation
-- Automatic blur placeholder generation
-- CDN optimization ready
+- Native lazy loading (supported by all modern browsers)
+- No runtime JavaScript overhead

+- Use [Cloudflare Images](https://www.cloudflare.com/products/cloudflare-images/) service
+- Use [Cloudflare Transform API](https://developers.cloudflare.com/images/transform-images/)
+- Pre-optimize images before uploading to R2
 
 **Files Modified:**
 - `next.config.mjs`
+- `components/hero-section.tsx`
+- `components/artists-section.tsx`
