how can i make this background transparent

[NZ_Kiwis]

here is my gd code - currently it's got a white background around the text

$font = "AnnabelScript.ttf";
$white = imagecolorallocate($image, 0, 0, 0);
imagettftext($image, 30, 0, 15, 440, $white, $font, "56%");

actually the background on this image is transparent

It must be - I can't see the image at all.

I can't even see how it's being created or how it's being saved.
