For me it looks exactly in Chrome like in Firefox. For this kind of website i would use WordPress to build it For me this looks like custom html website. I don't like how everything is aligned in center, but i like minimalistic look and color you choose. I would put istockphoto link, collections, contact details, keywords, inline in footer separated in 4. And bigger slideshow with more info on website. And take a look at header when you browsing different collections. It breaks on some pages and goes to the left.
Everything south of the second vertical black line can be deleted as it's just duplicating the links above and full addresses/numbers are never advisable and no user needs to see keywords either.
Also you have committed the cardinal sin that makes me scream every time I see it. Please don't make a user scroll, just to see a couple of lines of text. Make it fit to 100% height or only use scroll bars unless it is impossible for information to fit neatly on one page.
Displays nicely in FF12 on linux by the way.
