The first impression on landing is that it is quite a simple and attractive presentation. This is what is vitally important to first-time visitors.
Thumbnails are of a balanced size on 1024x768 displays and no problem visually with that. There is not of course any such thing as designing websites for wide screens: the code will take care of rendering and stretch. At the moment the page content is left-centric; I would be inclined to spread it out (centre it) over the top and add additional links; this will reduce the impact of a lot of blank area.
In the code behind the page, beef it up later toward completion with the suggested codec below:
(presently):
<html>
<head>
<title>The Flying Camera - photographs by Scott Davis</title>
</head>
to—
<meta name="AUTHOR" content="Scott Davis, The Flying Camera" />
<meta http-equiv="CONTENT-TYPE" content="text/html; charset=windows-1252" />
<meta http-equiv="CONTENT-LANGUAGE" content="en-us" />
<meta http-equiv="PRAGMA" content="no-cache" />
<meta http-equiv="EXPIRES" content="text" />
<meta name="REVISIT INTERVAL" content="14 days" /> 14 days can be anything; most webbots index daily or 4, 7, 12 14, 21, 28 or 31 days.
<meta name="ROBOTS" content="index,follow" />
<meta name="KEYWORDS" content="Scott Davis, photography, fine art, landscape, alternative processes, display, tarot, figure studies, still life, active, Hercules, mythology, interpretations" />
<!--as many keywords as you can dream up; you never can have too many--!>
The above code is only very necessary for the home (or index) page. Robots land on that and follow the site hierarchy downward, gathering information (the "meta uptake"). So a netizen then searches in Google for Scott Davis and if your name is there, you're going to be the first search result! How that happens depends a lot on the information you put on the page and behind it (in the code).
All your images should have descriptive names (e.g. definitely not 1234_a.jpg) and alternate text (the text that pops up when the mouse moves over it) that assists not just indexing agents (Google, among) but also viewers. Each page should also have a lot of descriptive text for much the same reason just given. Webbots also index Flash content but that content must also have a descriptive identifier.
Employing Flash is a better choice than relying on Javascript, which is often blocked by browsers (by default or via user-negotiable add-ons e.g. in FireFox and Opera), leaving netizens wondering what is wrong; thus their interest wanes and they move onto a competitor's website.
All said and done I like what I see and reckon it will be a very attractive 'front door' for you as it progresses.
