What are the potential performance issues when repeatedly displaying a large number of small images using PHP?

Repeatedly displaying a large number of small images using PHP can lead to performance issues due to the overhead of loading and processing each image file. To improve performance, you can use image caching to store processed images and reduce the number of times they need to be generated. 

// Example of using image caching to improve performance when displaying small images

function displayImage($imagePath) {
    $cachePath = 'cache/' . basename($imagePath);

    if (!file_exists($cachePath)) {
        // Process and save the image to the cache
        $image = imagecreatefromjpeg($imagePath);
        imagejpeg($image, $cachePath);
        imagedestroy($image);
    }

    // Display the cached image
    echo '<img src="' . $cachePath . '" alt="Image">';
}

// Usage
$imagePath = 'images/image.jpg';
displayImage($imagePath);
