Why Images Hurt App Performance & How the New Next.js Image Component Can Help
summary
Explains five concrete image pain points and specific fixes: automatic srcset generation and CDN + Next Image Optimizer integration to serve responsive sizes, modern-format switching (WebP/AVIF, ~25–35% savings), an intersection-observer lazy-loading default, a priority preload attribute that inserts link rel=preload for hero images, and enforced width/height aspect ratios at build time to eliminate layout shift. Component ships in Next 10 and claims to reduce LCP and cumulative layout shift by applying those tools automatically.
