I don't know enough about HTTrack to help with it, but perhaps you could try
alternate approaches. the problem might be that the photos seem to be in a
database and each display just calls the various photos according to which
category you have picked. If you just want the photos I have tried a freeware
program called PicPluck! and it will capture the full images of the thumbnails
displayed on each page.

Another approach if you want all the comments is to display each page and use
a screen capture program. The one with Ulead Photo Impact (great program) can
be set to scroll the page so off screen stuff is captured.
There are also progs to save several html pages as a group, unlike your
browser which only saves one page.
