Why???? Yes, flash looks neat, but remember that a lot of company networks don't allow flash enabled websites, and a lot of the world doesn't have broadband, making many flash sites too cumbersome to view.
I'm sorry I can't help you with your question, but just as a consideration, if you do create a flash-enabled website, ensure that you create a non-flash companion site or risk losing a lot of traffic.
Yep then there are some people who open the website see the flash loading sign and just close it again because they don't feel like waiting for the thing to load.
Make sure if you consider flash you do it right. It should be simple, fast, and not distract from the photos. I've seen oh so many pretty photographer's website that makes it really hard to navigate their site. But it certainly looks like they are good at webdesign.
