I've been away for a few days, but now I've had a chance to play with your website in Opera 9.64, Firefox 3.0.7, Safari 3.2.2, and IE 7.0.6001, all running under Vista. Almost everything works very well, and the site is clean and very elegant. The tiny glitches I encountered were both in Opera and IE: When viewing a single image in a gallery, the left- and right-arrows for "next" and "previous" image don't appear for some reason (they do in both Firefox and Safari). So in IE and Opera I had to move the mouse around until it happened to hit on "Previous", "Next", and "Close" just below the image. But those are very tiny and so dark they almost disappear into the background until the mouse hovers over them. I would suggest using a little bigger font and a slightly lighter color for those links, so they can be easily spotted even in IE or Opera. A tad larger and brighter still won't detract from the elegance of the page, IMHO.
Also: As someone else suggested, why not use "Galleries" instead of "Archive"?
Finally, I won't get to see the new gallery on April 5, as I will be away for three weeks. But I'll check on it when I get back from Utah in late April.
As I've said before, your work is gorgeous, and the website presents it very nicely.
