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;

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;
