Scenario in TimThumb where it fails to get the correct docRoot in the function calcDocRoot.

This was reported to me so I'm passing it on...

TimThumb where it fails to get the correct docRoot in the function 
calcDocRoot.. Basically rather than add a bunch of additional logic to handle 
strange setups I define an optional global in timthumb-config.php and check for 
it in timthumb.php on line 800 Here is the new calcDocRoot function:

protected function calcDocRoot(){
if(!defined("TIM_DOCROOT")){
$docRoot = @$_SERVER['DOCUMENT_ROOT'];
if(!isset($docRoot)){ 
$this->debug(3, "DOCUMENT_ROOT is not set. This is probably windows. Starting 
search 1.");
if(isset($_SERVER['SCRIPT_FILENAME'])){
$docRoot = str_replace( '', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 
0-strlen($_SERVER['PHP_SELF'])));
$this->debug(3, "Generated docRoot using SCRIPT_FILENAME and PHP_SELF as: 
$docRoot");
} 
}
if(!isset($docRoot)){ 
$this->debug(3, "DOCUMENT_ROOT still is not set. Starting search 2.");
if(isset($_SERVER['PATH_TRANSLATED'])){
$docRoot = str_replace( '', '/', substr(str_replace('\', '', 
$_SERVER['PATH_TRANSLATED']), 0, 0-strlen($_SERVER['PHP_SELF'])));
$this->debug(3, "Generated docRoot using PATH_TRANSLATED and PHP_SELF as: 
$docRoot");
} 
}
if($docRoot && $_SERVER['DOCUMENT_ROOT'] != '/'){ $docRoot = 
preg_replace('//$/', '', $docRoot); }
} else {
$docRoot = TIM_DOCROOT; 
}
$this->debug(3, "Doc root is: " . $docRoot);
$this->docRoot = $docRoot;
}

you'll see it is checking for a constant called TIM_DOCROOT... Here is a sample 
definition:

define ('TIM_DOCROOT','D:Inetpubwwwsites');

if it isn't needed just comment that line out.

Hi - this has existed since December 5th. The constant is called

LOCAL_FILE_BASE_DOCROOT

set that and you can override the docroot of the script
