Some observations:
1) The site is not standards-compliant and does not validate as valid HTML. This means that the site doesn't necessarily look and behave the same in all browsers. You can see the validation results and generated errors here:

Why is it important to create valid HTML (and CSS for that matter)?
In the attached image "firefox-gallery.jpg" is what I see with Firefox.
In the attached image "opera-gallery.jpg" is what I see with Opera.
I have no Safari here, but by experience I'd say it resembles what I see with Opera (ie. probably not what is intended).
2) Many people (me included) don't use pure white as the color of their choise as active window background color. This means that the image-elements that are designed to show on white background look ugly if the page explicitly doesn't set the background color. This is illustrated in the attached "Image1.jpg" image. The fix is to include background color information in the body tag.
3) You have included no meta-information that would help indexing services (like Google) to assign your site keywords. This has no importance unless you desire your site more visibility in search engines.
Other than those ... looks good.
Keeping the structure simple, easy to navigate and without any annoying effects that draw attention away from the content (like blinking stuff, animated gifs etc) is the way to go in my opinion. Personally I like to avoid complex scripting myself (and boy the scripts do look a bit overwhelming for this kind of site!) unless there is absolutely no way to represent the information otherwise, but I guess that's a matter of taste (and also your site doesn't work in browsers that have disabled JavaScript execution - I don't see why your site NEEDS it because using Cascading Style Sheets would achieve pretty much the same net results anyway).
