you need 'enable' transparency.

$string = "username"; $string2 = "example.com"; $image = imagecreatefrompng("http://i.imgur.com/y6hwkkw.png"); $cor = imagecolorallocate($image, 0, 0, 0); $background = imagecolorallocate($image, 0, 0, 0); imagecolortransparent($image, $background); imagealphablending($image, false); imagesavealpha($image, true); imagestring($image,5,126,22,urldecode($string),$cor); header('content-type: image/png'); imagepng($image,null);
