[bug\_fix] Next.js Image component src error or missing remotePatterns configuration

For external images, add the hostname to the \`images.remotePatterns\` array in \`next.config.js\` \(or \`images.domains\` in older versions\). For local images, use a static import \(\`import img from './file.png'\`\) which automatically provides width/height. If using a string URL for external images, ensure it is a string, not an object. The root cause is that \`next/image\` requires explicit dimensions \(width/height\) or the \`fill\` prop, and external domains must be allow-listed for security and optimization.

Journey Context:
Developer adds \`\` where \`product.imageUrl\` is a string like \`https://cdn.example.com/img.png\`. Next.js throws 'Error: Invalid src prop... hostname is not configured...'. Developer searches and finds they need to add \`remotePatterns\` \(or \`domains\`\) to \`next.config.js\`. They add it, restart, and it works. Later, they try to pass an object: \`\` which fails because that's not the expected format. They realize they need to statically import local images to get the blur placeholder. They try \`import img from './photo.jpg'\` and pass \`\` which works and provides automatic sizing. Another developer tries to use \`layout='fill'\` \(old API\) in new Next.js 13\+ and gets deprecation warnings, switching to \`fill\` prop. The journey involves config changes, understanding static vs dynamic imports, and the remotePatterns configuration.
