	      $img = imagecreatetruecolor(200, 200);

	      // allocate some colors

	      $red   = imagecolorallocate($img, 255,   0,   0);
	      $green = imagecolorallocate($img,   0, 255,   0);
	      $blue  = imagecolorallocate($img,   0,   0, 255);

	      // draw the head
	      imagearc($img, 100, 100, 200, 200,  0, 360, $white);
	      // mouth
