i've got a similar problem. I was downloading about 11GB's of pictures, without
html files. Soon I realized that it would be very useful to have an index of
those pictures, which btw exists one that website (on page one level up), and
set the program to download only html files one level up, winhttrack started
to download the pictures all over again. I don't know how to configure the
program so it doesn't download files which it already downloaded.
Anybody?
