This is what I use

It works on all browsers that I now of.
Dreamweaver keeps asking me if I want to use their code and
I always say NO.
Yes 99.9% of people (I just made that up) have flash on their computers. People that don't are probably not my demographic, so I don't care.
What I am careful to do, though, is to make my flash small...only part of a banner...see mine at
www.jacksononthemoon.com on the right hand side. Wringer Washers in Space...my signature cartoon!
Remember that while some browsers are apparently able to read actual text in flash, no browser can read the graphics, so be sure not to put anything important in the flash that search engines could not read.
