To use this function notice that 'image' parameter it's a RESOURCE and NOT an Image File Path !

Here comes an exemple:

$img = @imagecreatefromgif("http://www.mysite.com/my_imag.gif");

if ($img) $img_height = imagesy($img);

echo "My height is " . $img_height;

You should destroy the $img too...
So it would be :
$img = @imagecreatefromjpeg("http://www.mysite.com/my_image.jpg");

if ($img) {
 $img_height = imagesy($img);
 ImageDestroy($img);
}

echo "My height is " . $img_height;
