php d'upload de fichier move_uploaded_file() Failed to open stream

J'ai un fichier de script d'upload:

$allowedExts = array("gif", "jpeg", "jpg", "png");
$extension = end(explode(".", $_FILES["picture"]["name"]));
if ((($_FILES["picture"]["type"] == "image/gif") || ($_FILES["picture"]["type"] == "image/jpeg") || ($_FILES["picture"]["type"] == "image/jpg") || ($_FILES["picture"]["type"] == "image/png")) && in_array($extension, $allowedExts)):
    if($_FILES["picture"]["error"] > 0):
        echo "Error: " . $_Files["picture"]["error"];
    else:
        move_uploaded_file($_FILES["picture"]["tmp_name"], "/TnA/ProfilePics/" . $_SESSION['ID'] . "." . $extension);
    endif;
endif;

Mais j'obtiens l'erreur:

Warning: move_uploaded_file(TnA/ProfilePics/1.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/content/91/9848191/html/TnA/webservice.php on line 1067

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/php5nOdhI' to 'TnA/ProfilePics/1.jpg' in /home/content/91/9848191/html/TnA/webservice.php on line 1067

Voici mon fichier de structure:

Web Host Root (I have another site here)
    -TnA (Root of this site)
        -index.html
        -webservice.php
        -ProfilePics
            -(My target location)

Ce relative de l'url du répertoire dois-je utiliser? J'ai essayé ProfilePics/1.jpg et /ProfilePics/1.jpg fois de suite dans la même erreur.

EDIT:

À l'aide de:

move_uploaded_file($_FILES["picture"]["tmp_name"], dirname(__FILE__) . "ProfilePics/" . $_SESSION['ID'] . "." . $extension);

J'obtiens:

Warning: move_uploaded_file(/home/content/91/9848191/html/TnA/ProfilePics/1.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/content/91/9848191/html/TnA/webservice.php on line 1067
