title: Defer Images(Not Lazy Loading) NextJS
body: <p>I'm trying to lazy load images, but that doesn't load the images fast enough(nextJS and intersection observer). So, I've decided to defer my image loads for important images. In that way they should start loading as soon as the initial paint is done, but still not block the entire thread.</p>
  <p>How can this be done in NextJS?</p>
  <p>I've tried setting the image URL inside <code>useEffect</code>, but I'm not sure if it blocks the main thread. Does it?</p>
