Sorry to be asking so many questions all of a sudden; I've put a tremendous amount of work into overhauling my site lately. I think I've made a lot of progress, although I have plenty of work to go. But in the meantime, I have a navigation system that's less intrusive, and works.

My site is organized as a hierarchy, and UL/LI/UL/LI tags represent that better than just divs with a elements inside them. But it seems kind of like a return to tables, which I've been working hard to stamp out on even the more obscure pages on my site ... wrapping the real code ( the links ) in lots of extra tags.

So I was hoping I could talk people into having a look at the source for the navigation ( at the top of the page ) and giving me a second opinion about whether I'm over-using divs, or if there's a better way in general?

A good example would be Waterfall, Glacier National Park, Montana.

Thanks!

I would recommend starting by thinking about what the information is you are trying to present.
For example, a list of menu items is a good use for UL/LI (list items )

In a case where you are defining something like the section:

<h1>Cascading Falls, Glacier National Park</h1>        
        <div id="photographInfo">
            <div class="photoInfoLabel">Location:
...

I would use a definition list:

<dl>
        <dt>Cascading Falls, Glacier National Park</dt>
        <dd class="photoInfoLabel">Location: Glacier National Park, Montana</dd>
        <dd class="photoInfoLabel">Date: July 25, 2002</dd>
...

With some CSS you could eliminate most, if not all of the BR tags.

Just my thoughts

I agree The menu is definitely best done with lists, and the definition list is the way to go on the other. I've used DL's for several things and it works out well. I've floated DT's and DD's to place things where I want them.

Wow, that's not even what I was asking/worried about, and people gave me valuable feedback. This is the first I've heard of definition lists, so it sounds like I've got some reading to do. Quick question on that, before I start changing my code: I can still use width, padding, and margin to force the labels ( Location:, Date:, Exposure: ) and values ( Kansas, 1/1/04, etc ) to line up the way they are now?

The nav menus at the top of the page ( much better than on the left ), could anybody tell me why ULs and LIs are better suited? I sort of get the feeling I might be relying too much on divs for that, but I'm not sure how unordered lists would improve things?

And would the structure look something like this?

Galleries
> Landscapes
-> Rockies
-> Sierra
> Cityscapes
-> Seattle
Articles
...

With sets of ULs embedded inside LIs?

Absolutely. You can style each part of a DL - the DL itself, the DT and the DD elements. They are very versatile, I a DL here - on the Office Hours:

Your structure would be right:
<dl>
<dt>Landscapes</dt>
<dd>Rockies</dd>
<dd>Sierra</dd>
</dl>
