How can PHP beginners avoid common errors when trying to output text as graphics?

PHP beginners can avoid common errors when trying to output text as graphics by ensuring they have the necessary GD library installed, using the correct functions to create images, and properly setting the content type header. They should also remember to use the appropriate image format (e.g., PNG, JPEG) and handle errors gracefully. 

<?php
// Check if GD library is installed
if (!function_exists('gd_info')) {
    die('GD library is not installed');
}

// Create a blank image
$image = imagecreate(200, 50);

// Set the content type header
header('Content-Type: image/png');

// Output the image as PNG
imagepng($image);

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