I had a functioning background, until I embedded an .swf file on the page. Now the flash is hanging out in the top left corner, and it pushed the background image down below it. Why is the .swf file above the background, and not on it?

Here is my code:

(HTML - .swf)
<embed id="slideshow_0 1" width="550" height="400" allowscriptacce ss="always" allowfullscreen ="false"...
