Gif will always do hard backgrounds.

Youy may use PNG.

[code]
$img = imagecreatetruecolor($width, $height)
imageAlphaBlending($img, true);
imageSaveAlpha($img, true);
imagecolorallocate($img,0,0,0,127);
[/color]

This will make a transparent backgrounded PNG

You must note that MSIE 6 is the only browser that does not support them. 7 is said to do.
