Generating valid html code embedding Flash
I nearly gave up trying to keep my code valid and embed a Flash element into my page. (I had completely decided to ignore providing alternate content for users without flash).
But then I found SWFOject!
Not only was I able to embed the flash element I wanted, my code validated properly, and I was able to include a static image for users without flash or javascript enabled in their browsers.
Thank you Geoff Stearns for your help!
