How do you implement dynamic Open Graph images in Next.js (ImageResponse)?

Q: How do you implement dynamic Open Graph images in Next.js (ImageResponse)?

**TL;DR.** An opengraph-image.tsx file (or the ImageResponse API from next/og ) **renders JSX/CSS to a PNG** on demand, so you generate **per-page social share images** with dynamic content (title, author) — no design tool or external service. JSX + data title, author ImageResponse renders → PNG <r
