Not to pile on, but I agree that a Flash intro page is a bad idea. For example, I despise going to freestyle photo if I have to go through their maze to get to the actual site. I have bookmarked the inside page where you can actually start looking for things, but the intro page is very irritating and worthless in my eyes.

The same goes for static graphic intro pages. That was all the rage before Flash hit the scene, but it is no better than Flash, except in the cases where the files are smaller. Anything that gets in the way of the content loses you visitors.
