Resting Image on Flash Video?

I create swf image slideshows from a separate program that I want to embed in posts. That part is all working fine, but when I have it set to not auto-play, there’s a play button on a black screen, but I want to be able to have an image behind the play button (like you often see… on YouTube, etc), so users have some idea, visually, of what they will be watching. How is this possible? BTW, I’m using the Kimili plugin to embed the flash.

The black screen is definitely how it looks when I output it from my slideshow maker and I can’t see a way to change that part of it. Is there something I can do in WP though to change that? Or even a work around- like posting an image from the video with a play button over the top of it, and when you click the image, the flash movie starts to play? Seems like there should be an easier why than that though.

Please be aware that I’m a programming dummy and need things explained to be very simply, perhaps even with examples! Sorry about that. Thanks!
