The white square of doom!
Author: Shaunk...
I've had this issue for years. When swfs are embedded in a HTML page you get a flash of white before the content loads. You can override the background colour of the swf with HTML but this doesn't fix the problem. I've just found how to fix this!
"The white is the background for the Object, not the table, nor the div, nor the
body, the OBJECT."
So you have to set the background of the object aswell ie.
<embed src="file.swf" quality="high"
pluginspage="http://www.macromedia.com/go/getflashplayer"
type="application/x-shockwave-flash" width="550" height="400"></embed>
<param name="bgcolor" value="#000000" />
Sorted. I'm on a roll!
However, that said it's bloody hard work getting blogger to display formatted HTML.
