imagesx
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;
imagesy
(PHP 4, PHP 5)
imagesy — Ermittelt die Bild-Höhe
Beschreibung:
int imagesy
( resource
$im
)
ImageSY() ermittelt die Höhe des Bildes,
das durch im referenziert wird.
Siehe auch imagecreate() und imagesx().

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;
