Concept for Historical Photo Show: WordPress or Not?

OK, here’s my first attempt:

It goes some way to explaining what I hope to achieve,
in a general fashion. I have some ideas, but they’re flexible
to a degree, depending on what I decide is the best of
the available options. (Or what I’m persuaded)

There are hundreds of pictures involved. It seems that
grouping them by decade would be a good start. (Many
of them don’t have the year taken available). An Introductory
(front) page also seems appropriate.

Then a link to each decade (another page[s]?). Then some
sort of thumbnail slide show, with either auto or manual
advance. The ability to click a thumbnail for a larger
image. target="-blank" stuff. An option to jump to another
decade (page) if in the wrong era?

Usual place for comments. Moderated before being
visible, perhaps? Some sort of declaration that free use
with acknowledgement is OK?

Anything else?

I’m starting with a few vague concept notions, here. If
anyone else has “been there – done that,” please let me
know what you decided upon.

I’ve been told that there are a number of historical societies
which have implemented something like this. If anyone knows
of such, please point me in their direction.
