Report #22339

[bug\_fix] Invalid src prop \(https://example.com/image.jpg\) on \`next/image\`, hostname is not configured under images in your \`next.config.js\`

Add the external domain to the \`images.remotePatterns\` \(or legacy \`domains\`\) array in \`next.config.js\`, then restart the development server.

Journey Context:
Developer finds an image on a CDN like \`https://cdn.example.com/photo.jpg\`. They import \`Image\` from \`next/image\` and write \`\`. The page throws an error saying the hostname is not configured. Developer checks Next.js docs for Image Optimization. Learns that Next.js requires explicit permission for external images for security and to prevent abuse of the optimization API. They open \`next.config.js\`, add \`images: \{ remotePatterns: \[\{ protocol: 'https', hostname: 'cdn.example.com' \}\] \}\`. Restarts the dev server. Image loads correctly, optimized by Next.js.

environment: Next.js any version with \`next/image\`, especially when sourcing from external CMS/CDN. · tags: nextjs next/image remotepatterns domains external image cdn config · source: swarm · provenance: https://nextjs.org/docs/app/api-reference/components/image\#remotepatterns
