Problemi con graybox in script php

[akis]

Salve ragazzi,
sto ancora lavorando al mio album fotografico... tutto procede bene... ho pure inserito una funzione javascrit per ridimensionare l'immagine in base alla risoluzione del monitor ... però adesso non risco a far funzionare il tutto con greybox.

riporto integralmente lo script nella speranza che qualcuno mi aiuti a capire dove sbaglio:

greybox si apre.... però la foto non c'è chi aiuta?

<script type="text/javascript">
        var GB_ROOT_DIR = "../gallery/greybox/";
    </script>

    <script type="text/javascript" src="greybox/AJS.js"></script>
    <script type="text/javascript" src="greybox/AJS_fx.js"></script>
    <script type="text/javascript" src="greybox/gb_scripts.js"></script>
    <link href="greybox/gb_styles.css" rel="stylesheet" type="text/css" media="all" />
