[bug\_fix] Next.js Image component src prop type error or invalid src format

Ensure the \`src\` prop is either a statically imported image object \(from \`import img from './img.png'\`\) or a valid string URL. If using a static import, pass the imported object directly \(\`src=\{importedImg\}\`\), not \`src=\{importedImg.src\}\`. If using a remote URL, ensure the domain is configured in \`next.config.js\` \`images.remotePatterns\`. The root cause is that Next.js optimizes images and expects either a metadata-rich object \(from static import\) or a validated remote string; passing an unoptimized object or undefined causes build/runtime errors.

Journey Context:
Developer sets up a blog with Next.js. They create a PostCard component that receives an imageUrl prop. They use \`\`. For some posts, \`imageUrl\` is undefined initially \(loading state\). The component throws 'Invalid src prop'. They try to fix it with conditional rendering \`\{imageUrl && \}\`, but TypeScript complains. They then try to use a placeholder import, but pass \`src=\{placeholder.src\}\` which strips the metadata and causes blur placeholder to fail. They check the Next.js Image docs and realize that for static imports, they must pass the entire imported object, not just .src. For remote images, they must ensure the domain is whitelisted in next.config.js and handle undefined states with a fallback or conditional rendering outside the Image component.
