Next.js Image Component Causing Excessive Network Requests for Preloaded Images

next.js image-optimization performance javascript

I'm experiencing an issue with the Next.js Image component where preloaded images are causing excessive network requests, leading to performance degradation on my application. I have a gallery page that displays images based on user selection, and I'm trying to use the `layout='responsive'` property to ensure the images are displayed correctly. However, when the page loads, it seems to be fetching the same images multiple times instead of caching them. Here’s a simplified version of my code: ```javascript import Image from 'next/image'; const Gallery = ({ images }) => { return ( <div className="gallery"> {images.map((img) => ( <Image key={img.id} src={img.url} alt={img.alt} layout="responsive" width={600} height={400} priority={img.isFeatured} // Only for featured images /> ))} </div> ); }; export default Gallery; ``` I'm using Next.js version 13.2.0, and I've also enabled the `next/image` optimization feature in my `next.config.js`: ```javascript module.exports = { images: { domains: ['example.com'], }, }; ``` Despite these configurations, when I use Chrome's network tab, I can see that images that should be cached are being requested multiple times on page reload. I've tried using the `priority` prop for featured images but it doesn't seem to have an effect on the other images. Is there a way to better handle image preloading and avoid unnecessary network requests? Should I be using a different approach to caching or preloading images? Any insights would be appreciated! Thanks in advance!
