Five minutes up and running. It did take me another hour or so to get it tweaked for use on a site, but that's to be expected when you're customizing anything.
Part of me wants to take away a half star for the difficulty in locating documentation for the Lite version. Lots of links to upgrade, few if any links to documentation.
Even so, I've opted to go with the paid-for Developer version because I could see where I would want to use this on several sites down the road and it's so easy to use even non-technical people can add/edit slides.
