What are some recommended methods for optimizing image display in PHP scripts to prevent errors and improve performance?

To optimize image display in PHP scripts, it is recommended to resize images before displaying them to prevent errors and improve performance. This can be achieved by using the GD library in PHP to resize images to the desired dimensions before outputting them to the browser. 

// Load the image
$image = imagecreatefromjpeg('image.jpg');

// Get the original dimensions of the image
$width = imagesx($image);
$height = imagesy($image);

// Calculate the new dimensions for resizing
$newWidth = 300;
$newHeight = ($height / $width) * $newWidth;

// Create a new image with the new dimensions
$newImage = imagecreatetruecolor($newWidth, $newHeight);

// Resize the original image to the new dimensions
imagecopyresampled($newImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

// Output the resized image to the browser
header('Content-Type: image/jpeg');
imagejpeg($newImage);

// Free up memory
imagedestroy($image);
imagedestroy($newImage);
