What are the potential pitfalls of using lazy loading techniques in PHP to load images from a database in relation to website height?

Lazy loading techniques in PHP can lead to potential pitfalls related to website height when loading images from a database. If images are loaded lazily as the user scrolls down the page, the website's height may change dynamically, causing layout shifts and potentially impacting user experience. To address this issue, it's important to set fixed dimensions for the image containers to reserve space before the images are loaded.

<div style="height: 500px; width: 500px; overflow: hidden;">
    <img src="placeholder.jpg" data-src="image_from_database.jpg" style="width: 100%; height: auto;" />
</div>
