What function is missing in the PHP script to properly output the dynamic image?

The issue is that the PHP script is missing the function to output the image to the browser. To properly output the dynamic image, we need to use the `imagepng()` function to generate a PNG image and send it to the browser. 

<?php
// Create a blank image
$image = imagecreate(200, 200);

// Set the background color
$bg_color = imagecolorallocate($image, 255, 255, 255);

// Set the text color
$text_color = imagecolorallocate($image, 0, 0, 0);

// Add text to the image
imagestring($image, 5, 50, 50, "Dynamic Image", $text_color);

// Output the image to the browser
header('Content-Type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
?>
