next.js image-loading performance javascript

I just started working with I'm deploying to production and I just started working with I'm experiencing an scenario with the Next.js Image component where images above the fold are not being preloaded as expected. I have set the `priority` prop to `true` for images that I want to preload, but it doesn't seem to make a difference. The images are still taking time to load when the page is rendered, causing noticeable delays in the initial viewport rendering. Here's a snippet of my code: ```jsx import Image from 'next/image'; const HeroSection = () => { return ( <div style={{ position: 'relative', height: '500px' }}> <Image src="/images/hero-bg.jpg" alt="Hero Background" layout="fill" objectFit="cover" priority={true} /> </div> ); }; ``` I've also confirmed that the `next/image` version is `12.0.7` and I have set `experimental.appDir` to `true` in my `next.config.js`. I tried testing the performance with Lighthouse, and it still reported that images were not being preloaded efficiently. I checked the network tab, and the images are being fetched after the main content is rendered, which is contrary to my expectations with the `priority` prop. Could this be related to the way I'm structuring my component or how the layout is set up? Any insights on how to ensure images above the fold are preloaded properly would be greatly appreciated.
