Description:
------------
When using either imageSX or imageSY or imageCreateFromJpeg and etc.  The compiler does not allow imageSX('myimg.php?index=10') (Note: The file does exist and it is in the correct path)

Reproduce code:
---------------
for($i = 1; $i <= mysql_num_rows($result) ; $i++) {

$record = mysql_fetch_row($result);
$pics[$i]['src'] = "pg_im_full_by_id.php?ind=".$record[0];
			
$newIMG = imagecreatefromjpeg('pg_im_full_by_id.php?ind='.$record[0]);

$pics[$i]['width'] = imageSX($newIMG);
$pics[$i]['height'] = imageSY($newIMG);

}


Expected result:
----------------
Create an image using the source file, take its attributes and assign to the array.

Actual result:
--------------
Warning: imagesx(): supplied argument is not a valid Image resource
