What are the drawbacks of saving dynamically generated images as separate files for temporary use?

Saving dynamically generated images as separate files for temporary use can lead to issues with storage space, file management, and security risks. Instead, a better approach would be to generate the image on-the-fly and serve it directly to the client without saving it as a file. This can help reduce the overhead of managing temporary files and ensure that sensitive data is not stored unnecessarily on the server. 

// Generate image on-the-fly and serve it directly to the client
header('Content-type: image/png');
$image = imagecreate(200, 200);
$bgColor = imagecolorallocate($image, 255, 255, 255);
$textColor = imagecolorallocate($image, 0, 0, 0);
imagestring($image, 4, 50, 50, 'Dynamic Image', $textColor);
imagepng($image);
imagedestroy($image);
