[bug\_fix] Next.js Image component missing required props or remotePatterns

For local images, provide explicit width and height to prevent layout shift, or use the fill prop with CSS sizing. For external images \(CDNs, CMS\), add the hostname to the images.remotePatterns array in next.config.js.

Journey Context:
You copy a standard tag into your Next.js 14 project: . You decide to use the optimized next/image for better performance, so you import Image from 'next/image' and replace the tag. Immediately, TypeScript and the dev server complain that width and height are missing. You try adding fill instead, but then you get errors about missing parent position:relative. You consult the docs and learn that for local images, Next.js needs explicit dimensions to calculate aspect ratio and prevent CLS, unless you use fill which requires the parent to have defined dimensions. You add width=\{800\} height=\{600\} and the error disappears. Later, you try to load an image from a headless CMS like Contentful. You get an error stating the hostname is not configured. You add the domain to next.config.js under images.remotePatterns \(or the legacy domains field\) and restart the dev server. The external images now load with Next.js optimization.
