image resizing and saving

[Fedde <php@2b4ever.net>]

heyas
i have the following code to resize an image to any wanted size:
<?
//$image2 = "image.jpg";
function resizeThatPic($image2){
	$maxheight = 100;
	$maxwidth = 100;
	$size = getimagesize ("$image2");
	$ratio = ($maxheight/$size[1]);	
	$constrain_width = ($ratio * $size[0]);
	$constrain_height = ($ratio * $size[1]);
	if ($constrain_width > $maxwidth){
		$mess = ($maxwidth/$size[0]);	
		$constrain_width = ($ratio * $size[0]);
		$constrain_height = ($ratio * $size[1]);
	}
	$image = imagecreate($constrain_width,$constrain_height);
	$colorblue = imagecolorallocate($image, 0, 0, 255);
	imagefill($image, 0,0, $colorblue);
	
	if(!($image2 = @imagecreatefromjpeg("$image2"))){
		$image = imagecreate($constrain_width,$constrain_height);
		$colorwhite = imagecolorallocate($image, 255, 255, 255);
		$colorblack = imagecolorallocate($image, 0, 0, 0);
		imagefill($image, 0, 0, $colorwhite);
		imagestring($image, 4, 10, 10, "Couldn't load image!", $colorblack);
		header("Content-type: image/jpeg");
		imagejpeg($image);
		exit();
	}
	
	imagecopyresized($image, $image2 , 0, 0, 0, 0, $constrain_width, 
$constrain_height, imagesx($image2), imagesy($image2));
	header ("Content-type: image/jpeg");
	imagejpeg($image);
}
?>

question 1:
I want to use this in an other page:
<?
require ("imagetest.php");
resizeThatPic("image.jpg");
resizeThatPic("image2.jpg");
?>
The problem is that this only shows a resized image.jpg and no image2.jpg 
at all, why is that? and what can i do about it?

question 2:
Is there a way to save the resized image to another directory on the server?

Thanks in advance :)
