Pop up Flash Banner

I have been doing Banners for my client for a few month and they recently made the request that they would like their banners to pop up in a new window. I checked out Kirupa’s tutorial “Centered Pop-Up Window”. I want it to pop up right away, without hitting a button, so I took that part of the script out.

I have never done a pop up banner before so I am a little lost.

I heard a little about geturl and target = blank.

any info would be appreciated.
