next.js image performance react JavaScript

I'm having trouble with I'm reviewing some code and I recently switched to I'm experiencing an scenario with the Next.js Image component (v12.1.0) where lazy loading is not functioning as expected when images are outside the viewport. I've set up my images to be loaded lazily using the `loading='lazy'` attribute, but they are still being loaded immediately on page render, which is affecting performance. Iโ€™ve tried adjusting the `priority` prop to false and have also confirmed that my `next.config.js` is correctly configured for image optimization. Hereโ€™s a snippet of my code: ```jsx import Image from 'next/image'; export default function ImageGallery() { return ( <div className='gallery'> <Image src='/images/pic1.jpg' alt='Picture 1' width={500} height={300} loading='lazy' /> <Image src='/images/pic2.jpg' alt='Picture 2' width={500} height={300} loading='lazy' /> <Image src='/images/pic3.jpg' alt='Picture 3' width={500} height={300} loading='lazy' /> </div> ); } ``` Iโ€™ve also checked the console and the Network tab, and I see that all images are being fetched on initial load, despite them not being in the viewport. Iโ€™ve cleared the cache and tested this on multiple browsers, but the question continues. Is there something I might be overlooking in the configuration, or is there a specific way to ensure that images are optimally lazy-loaded only when they enter the viewport? Any guidance would be appreciated! Any advice would be much appreciated. This is for a application running on Ubuntu 20.04. I'm open to any suggestions.
