In what ways can PHP scripts be optimized to efficiently handle the display of multiple images with specified dimensions?

To efficiently handle the display of multiple images with specified dimensions in PHP, you can optimize your scripts by using caching techniques to reduce server load and improve performance. Additionally, you can resize images on the fly using PHP libraries like GD or Imagick to generate thumbnails or resized images on the server side, rather than relying on the browser to resize them. 

// Example code snippet using GD library to resize images
function resizeImage($source, $destination, $width, $height) {
    list($sourceWidth, $sourceHeight) = getimagesize($source);
    $sourceImage = imagecreatefromjpeg($source);
    $resizedImage = imagecreatetruecolor($width, $height);
    imagecopyresampled($resizedImage, $sourceImage, 0, 0, 0, 0, $width, $height, $sourceWidth, $sourceHeight);
    imagejpeg($resizedImage, $destination);
    imagedestroy($sourceImage);
    imagedestroy($resizedImage);
}

// Usage
resizeImage('original.jpg', 'resized.jpg', 100, 100);
