Image Component in Next.js is Not Optimizing Large JPEGs for Performance

next.js image-optimization performance JavaScript

I'm having trouble with I'm maintaining legacy code that I tried several approaches but none seem to work..... I'm using the Next.js `Image` component to render a large JPEG image (about 5MB) on my homepage. Despite setting the appropriate `width` and `height` attributes, the image is taking an unusually long time to load, causing a significant delay in rendering the rest of my content. I've tried various formats, but the JPEG seems to be the largest contributor to the issue. Hereโ€™s the code I'm using: ```jsx import Image from 'next/image'; const HomePage = () => { return ( <div> <h1>Welcome to My Site</h1> <Image src="/images/large-image.jpg" alt="A large image" width={1200} height={800} priority /> </div> ); }; export default HomePage; ``` Iโ€™ve also enabled `next/image` optimization in my `next.config.js` like this: ```javascript module.exports = { images: { domains: ['example.com'], minimumCacheTTL: 60, }, }; ``` However, Iโ€™m still encountering a Core Web Vitals report showing a poor LCP (Largest Contentful Paint) score, and the image appears to be the bottleneck. Iโ€™ve examined the network tab, and the loading time for this image is noticeably high. I considered using a smaller image or a different format like WebP, but I wanted to retain the quality this JPEG provides. Has anyone faced a similar issue or can suggest any optimizations for handling large JPEG images with the Next.js `Image` component? Also, is there any configuration I might be missing that could help improve this situation? Any insights would be greatly appreciated! This is my first time working with Javascript LTS. I'm using Javascript 3.11 in this project. Thanks for any help you can provide! I'm working on a web app that needs to handle this. Hoping someone can shed some light on this.
