Looking into this...

You can do it easily on Windows with ASP.NET if that's an option for you...

I dont know but what about ImageMagick and other duilt in php scripts?

This is a function I used once for an image upload script. It works really well, the only thing I don't know how to do is how to preserve transparency (in gifs and pngs) when generating the thumbnail.

function createthumb($name,$filename,$new_w,$new_h){

	$system=explode('.',$name);

	if (preg_match('/jpg|jpeg|JPG/',$system[1])){

		$src_img=imagecreatefromjpeg($name);

	}

	if (preg_match('/png|PNG/',$system[1])){

		$src_img=imagecreatefrompng($name);

	}

	if (preg_match('/gif|GIF/',$system[1])){

		$src_img=imagecreatefromgif($name);

	}




$old_x=imageSX($src_img);

$old_y=imageSY($src_img);
If($old_x <= $new_w && $old_y <= $new_h){



	$dst_img=ImageCreateTrueColor($old_x,$old_y);

	imagecopyresampled($dst_img,$src_img,0,0,0,0,$old_x,$old_y,$old_x,$old_y); 
	if (preg_match("/png/",$system[1]))

	{	

	imagepng($dst_img,$filename); 

	} 

	if (preg_match("/gif/",$system[1]))

	{

	imagegif($dst_img,$filename);

	}

	else {

	imagejpeg($dst_img,$filename); 

	}





}else {

if ($old_x > $old_y) {

	$thumb_w=$new_w;

	$thumb_h=$old_y*($new_h/$old_x);

}

if ($old_x < $old_y) {

	$thumb_w=$old_x*($new_w/$old_y);

	$thumb_h=$new_h;

}

if ($old_x == $old_y) {

	$thumb_w=$new_w;

	$thumb_h=$new_h;

}



$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);

	imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 





if (preg_match("/png/",$system[1]))

{

	imagepng($dst_img,$filename); 

} 

if (preg_match("/gif/",$system[1]))

{

	imagegif($dst_img,$filename);

}

else {

	imagejpeg($dst_img,$filename); 

}

imagedestroy($dst_img); 

imagedestroy($src_img); 

}
}

Yeah, ImageMagick is your best bet
