alreet Zenners?

anyone ever played with this before?
highslide.com

I was thinking about installing zen lightbox because im not too keen on the standard image pop up as it shows a URL... but then im really not a fan of the whole lightbox effect on any website... but im impressed with the highslide js effect

however, i have IH2 installed.. so before i go and spend a few hours/days playing,. i thought i would ask if anyone knows of any conflict with IH2 and highslide js.. and saving me hours/days of hair pulling moments.
