What are the differences between static and dynamic images in Next.js?

What are the differences between static and dynamic images in Next.js?

In Next.js, static images are pre-rendered at build time, while dynamic images are generated at runtime. Static images are faster and better for performance, but dynamic images allow for more flexibility and can be updated without redeploying.

Can you give me examples of when to use each type?

Sure! Use static images for assets that don't change often, like logos or icons. Use dynamic images for user-uploaded content or images that change frequently, like product photos in an e-commerce site.

How does using dynamic images affect performance?

Dynamic images can slow down performance since they require server processing at runtime. However, with proper caching and optimization, you can mitigate these effects.

What tools or methods can I use to optimize dynamic images?

You can use image optimization libraries like ImageKit or Cloudinary, and implement lazy loading to improve performance for dynamic images.
