Hi,

Just noticed that getimagesize() is returning wrong value in case of PNG:
Array
(
    [0] => 1125
    [1] => 651
    [2] => 3
    [3] => width="1125" height="651"
    [bits] => 8
    [mime] => image/png
)

[2] => should return 4


As per: 
gd.php line 1805
define ('IMG_PNG', 4);


Test script:
---------------
$imgInfo = getimagesize("test.png");

if ($imgInfo[2] == IMG_PNG)
{
   echo "CONDITION SHOULD BE WORKING AS PER gd.php";
} 
else
{
   echo "CONDITION NOT WORKING";
}

Expected result:
----------------
CONDITION SHOULD BE WORKING AS PER gd.php

Actual result:
--------------
CONDITION NOT WORKING
