Looking for a program (free or commercial) to create complex html picture albums

I want to create a CD (and in the future a website) with pictures of several
categories.
They are all fractal images (mathematical images) but different types,
different coloring scheme's, different 'moods' and so on...

To make the cd a little bit platform independent, I want to add a html based
menu.

The pictures will be placed in a directory structure on the cd (or
web-site), like this:

Autorun <dir>
... some files for a windows cd-autorun menu ...
Images <dir>
Category 1 <dir>
Collection 1a <dir>
... pictures ...
Collection 1b <dir>
... pictures ...
Collection 1c <dir>
... pictures ...
and so on...
Category 2 <dir>
Collection 2a <dir>
... pictures ...
Collection 2b <dir>
... pictures ...
and so on...
and so on...
Programs <dir>
... small viewing tools and some fractal-image creation program(s)

Do you know a good program which can create html pages, correctly linked to
each other so I can create a 'menu' with the same structure as the directory
structure?
The first page should be the main page for all the categories (call it the
index.html file) which has a bitmaps, button, text-link or whatever for each
Category.
Each of the bitmap/buttons/whatever should link to another page with
bitmaps/buttons/whatever for each collection inside the category.
And, offcourse, in each collection I want to see thumbnails of all pictures
inside the corresponding collection directory.
That last step should be a multi-page index because the collection
directories contain lots of images.

I have already found a few programs, but so far, they all create good (or
bad) index pages just for ONE directory at a time and no html pages for
categories and collection (or sub-categories, whatever you want to call
them).
Linking all this manually is a lot of work, especially since the contents
isn't finished yet and I am still shuffeling, renaming and moving the
categories around a little bit.

Oh, and it should be for Windows.

Thanks in advace for all tips and links.
