Embedding a Flash Banner into WordPress

I am having a devil of a time embedding a flash banner into my wordpress site. I’ve read into other threads dealing with this issue but I’m a novice at this and I’m not really sure what to do with the info. Someone wrote to use the following code in the file that you would like the banner to appear but they gave no reference as to exactly where to drop in the code.

<object width=”XXX” height=”XXX”>
<param name=”movie” value=”filename.swf”>
<embed src=”filename.swf” width=”XXX” height=”XXX”>
</embed></object>

Most people said to use the Kimili plug in to embed flash, which I have done, but again, it doesn’t really do anything for me. I’ve input the info on Kimili and updated the options but it doesn’t exactly do anything. Maybe it’s not compatible with WordPress 3.2.1 because I don’t see any other options or settings to adjust or I just plain don’t know how to use it?

Anyway, I realize this topic has been touched upon before, but the previous threads that I have discovered have been closed and I need help with this. Any help I can get would be greatly appreciated.

Thanks.
