Images work locally but fail after deploy.
Logs mention invalid src prop or hostname not configured.
Static export fails with image optimization routes.

What to check first

Platform: Next.js + Vercel
Error: Image optimization error

Next/Image failures often come from missing remotePatterns or using optimization with static export. Configure allowed image hosts or disable optimization for static export.

Step-by-step fix

Add remotePatterns or domains in next.config.js.
For static export, set images.unoptimized when needed.
Check external image URLs include protocol and hostname.
Redeploy and test a page with the failing image.

module.exports = {
  images: {
    remotePatterns: [{ protocol: "https", hostname: "images.example.com" }]
  }
}

Common mistake to avoid

Do not allow every remote host unless you understand the security and caching impact.
