Error using phpThumb with - Page 1

Great class!

...but I receive and error using some thumb generated on-the-fly with phpThumb.

ERRORE n°6
File : C:\Inetpub\wwwroot\HWD.IT\adm\html2pdf\html2pdf.class.php
Linea : 2313
Impossibile caricare l'immagine phpThumb/phpThumb.php?h=150&src=/img/locandine/208324cd1ad237e186-la-locandina-di-20-sigarette-172312.jpg

(It means that could not load the image)

...and I call the image in this way

<img src="phpThumb/phpThumb.php?h=150&src=/img/locandina.jpg">

With the "normal" pages, everything works fine... so I assume that the installation is correct.

Any idea how to solve this problem? There is a yet know problem with the php-generated images?

I'm using the 3.31 version (because i'm with php4)

Tnx a lot

P.S. Sorry for my english

it could be because the relatif path to phpThumb is not the good one

But the html version of the page works fine so phpThumb configuration must be correct!

I guess if html2pdf is look for phisical path of the image... in this case it would never find the original file!

look at the example 9
