Next.js image optimization requires setting explicit width and height for static images or using fill for responsive containers to prevent layout shift. Apply priority loading to LCP elements and specify responsive sizes to ensure efficient loading across devices.

The best way to handle responsive Next.js images with fill is to pair the fill property with explicit sizes attributes on a relatively positioned parent container. This allows the image to scale correctly across breakpoints while maintaining proper aspect ratios.

You add blur placeholders for Next.js images by leveraging built-in placeholder properties for static imports or configuring blurDataURL for remote images. This provides a low-resolution preview while the full image loads, improving perceived performance.

You configure next.config.js for remote images by defining remotePatterns to safely whitelist external domains and specifying a custom loader function. This setup ensures images are properly optimized and served through your chosen content delivery network.

Yes, Next.js image optimization works with internationalized alt text by passing translated strings directly into the alt attribute. This approach maintains accessibility standards while supporting multi-language workflows.
