What are some best practices for ensuring that images can be viewed in their large version only after the page is fully loaded?

To ensure that images can be viewed in their large version only after the page is fully loaded, one best practice is to use JavaScript to dynamically load the larger images after the page has finished loading. This can help improve page load times and prevent users from seeing blurry or incomplete images while the page is still loading. 

<script>
window.addEventListener('load', function() {
    // Select all the small images on the page
    var images = document.querySelectorAll('img');

    // Loop through each image and replace the src attribute with the data-src attribute
    images.forEach(function(img) {
        img.src = img.getAttribute('data-src');
    });
});
</script>
