$image = imagecreatefromJPEG("image.jpg");

// set colors
$white 	= ImageColorAllocate($image, 255, 255, 255);
$black 	= ImageColorAllocate($image, 0, 0, 0);

imagettftext($image, 50, 0, 70, 140, $black, 'arial.TTF', $the_code);

// created image 
imagejpeg($image);
imagedestroy($image);

 

the first line reduces the image quality
