PHP problema con uno script di galleria immagini scaricato

[Manson666]

Ho scaricato questo script che crea una galleria delle immagini ma quando lo vado ad aprire mi da i seguenti messaggi di errore:

1) Warning: Division by zero in c:\programmi\easyphp\www\img\bpa\bpa.php on line 50

x
Thumbs.db

2) Warning: Division by zero in c:\programmi\easyphp\www\img\bpa\bpa.php on line 50

x
galleriab1.0.php

Può dipendere dal fatto che lo sto facendo girare in locale con Apache su WinXP e ci sono i Thumbsnails?

// - This script takes a directory full of images and displays them as thumbnails on the screen
// - Each thumbnail has a hyperlink to it's respective image (opens in a new window)
// - The only major drawback is that the browser loads the full size image into memory and then scales it down,
// which can be pretty slow on dial-up connections, depending upon image size and the server.
// - The image directory should not contain ANY FILES OTHER THAN JPG, GIF, PNG, or other browser compatible images!!!
//
// * Note * This is not a full-featured, fancy image gallery. With a little programming effort, however, it
// can become a very flexible photo album. This script is intended for those who wish to experiment
// with PHP and it's capabilities and for anyone who wants a backbone to work off of. Tested on PHP 4.
