Well, folks, I'm back again.
I have just uploaded the newest incarnation of my website, and once again I invite comments and critiques (in the high-minded and sensitive way that LuLa members are famous for -- except in certain threads). Thanks to Lois, I have immersed myself in CSS (ouch -- I'd really rather be out photographing, but then, learning PhotoShop was no picnic either), and I think the site works a good bit better now.
I am aware that I have still not implemented a few of the good suggestions I received from you kind people, but I do plan to make more tweaks in the future. Here are some items on my to-do list:
1. Put links back to the main Galleries page on each individual large image page (perhaps just add the navigation sidebar that now appears everywhere else), as Jeremy suggested.
2. Let the arrow keys (left, right, and up) navigate between "previous image", "index", and "next image". The problem is that So far I don't know a simple and foolproof way to do that. From what I've heard, the use of the arrow keys is highly browser- and even OS-dependent, which is a bummer.
3. Eventually I would like to bring my blog page inhouse. Currently it is one blogger.com, and my link to it opens in a new window. But I don't want to build my own blog system right now (I'd really rather be out photographing).
4. Take a look at the DTP Forum. But only after I've really been out photographing for a bit.
P.S. Those of you who made suggestions get a free mention on my "Credits and Links" page.
