Yeah, Good question. I'll edit my instructions above.
If you are already using JustDave's WONDERFUL popup Graemlin hack.... then this uses the SAME file. So you don't need to re-upload it.
I included it in this zip, rather than saying that the other hack was required, incase somebody didn't want it for their posting pages.... you can add it with this hack without having to fool with editing any other files.
