How can PHP developers optimize image processing scripts to prevent internal server errors and black images during resizing?

When resizing images in PHP, developers can optimize their scripts by setting appropriate memory limits and error handling to prevent internal server errors and black images. To avoid memory exhaustion, developers can use functions like `ini_set()` to increase memory limits and handle errors gracefully using try-catch blocks. 

// Set memory limit for image processing
ini_set('memory_limit', '256M');

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

// Check if the image was loaded successfully
if ($image !== false) {
    // Resize the image
    $resizedImage = imagescale($image, 200, 200);

    // Save the resized image
    imagejpeg($resizedImage, 'resized_image.jpg');

    // Free up memory
    imagedestroy($image);
    imagedestroy($resizedImage);
} else {
    // Handle error if image loading fails
    echo 'Error loading image.';
}
