What are some best practices for optimizing PHP scripts that involve fetching and displaying external images and data to improve performance and user experience?

When fetching and displaying external images and data in PHP scripts, it's important to optimize the process to improve performance and user experience. One way to achieve this is by caching the external images and data locally to reduce the number of requests made to external servers. Additionally, resizing and compressing images before displaying them can also help improve load times. 

// Example code snippet for caching external images locally
$imageUrl = 'https://example.com/image.jpg';
$localImagePath = 'cache/image.jpg';

if (!file_exists($localImagePath)) {
    $imageData = file_get_contents($imageUrl);
    file_put_contents($localImagePath, $imageData);
}

echo '<img src="' . $localImagePath . '" alt="External Image">';
