What are the potential pitfalls of including dynamic images like PNG in HTML tables in PHP, and how can they be avoided?

One potential pitfall of including dynamic images like PNG in HTML tables in PHP is that it can lead to slower page load times and increased server load, especially if the images are large in size or there are many of them. To avoid this, it is recommended to optimize the images before including them in the table, use lazy loading techniques to only load images when they are in the viewport, and consider using CSS sprites to combine multiple images into a single file. 

```php
// Example PHP code snippet to implement lazy loading for dynamic images in an HTML table
echo '<table>';
foreach ($images as $image) {
    echo '<tr>';
    echo '<td><img data-src="' . $image['url'] . '" class="lazyload" /></td>';
    echo '</tr>';
}
echo '</table>';
```

In this code snippet, we are using the `lazyload` class on the `img` tag and setting the image source to a `data-src` attribute. This allows us to implement lazy loading for the images, which will only load them when they are in the viewport, helping to improve page load times and reduce server load.
