What potential issue or pitfall is the user facing with the current script when trying to add text to the image?

The potential issue the user is facing with the current script is that the text color is not being set before adding text to the image, resulting in the text being added in the default color which may not be visible on the image. To solve this issue, the user needs to set the text color before adding text to the image. 

// Set the text color before adding text to the image
$textColor = imagecolorallocate($image, 255, 255, 255); // Set text color to white

// Add text to the image
imagettftext($image, 20, 0, 10, 50, $textColor, $font, 'Sample Text');

// Output the image
header('Content-type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
