"floating" flash banner

Hello, I´ve made a banner that would cover the whole web page for a few seconds, then it would just be a regular banner. The animation moves into the banner and stays there afterwards.
Everything works fin, but I have to send that to a few different people who will upload that to their websites.

I was just wondering what are the precautions I should have. I mean, do I just send them a .swf file that is 1024x768 with a transparent background?
