Report #64592

[bug\_fix] Invalid src prop on next/image with unconfigured domain

Add the domain to images.remotePatterns \(or legacy images.domains\) in next.config.js with protocol and hostname, or use a local image. For wildcard subdomains, use pathname patterns.

Journey Context:
Developer finds an image URL from Unsplash or Cloudinary and drops it into the component in their Next.js app. In development, they see an error overlay stating the hostname is not configured. They try to use a regular tag instead and it works, but they lose optimization. They search the error message and land on the Next.js docs for next/image. They learn about the remotePatterns configuration in next.config.js. They add the domain pattern \(e.g., protocol: 'https', hostname: 'images.unsplash.com'\), restart the dev server, and the image loads with optimization enabled.
