If you start HtTrack at the frontpage of that site it won't
get far !
After you select language on the website you get a form
where you can do a lot of input and press search - HtTrack
can not do these input - so it don't get past that page !
A trick here could be to start HtTrack at the page recieven
with an empty searh (press search without selecting
anything) - for the english language this results in this URL:
<http://catalogo.marazzi.it/RicercaRootNew.asp?codlingua=2&formato=2&codserie=*&codprodotto=*&codformato=*&codiceart=&codtipo=*&codutilizzo=*&coduso=*&codtecnologia=*&codresattchi=*&codresgelo=*&scivolamento=*&mohs=*&codpei=*&spessore=*&submit1=+Search>+
Stating from this URL HtTrack can crawl a lot of pages and
download a lot of images - with the right filters you should
be able to achieve what you want - remember that you must
allow HTML-files to keep crawling !
