This is a nice module which essentially slides 5 images over each other, which I didn't get from the demo as it looked like separate tabs and images. However it works very well and is easy to install and configure.
My problem was that you can't have fewer or more than 5 items, and I needed only 2. When I found this, I emailed support and had a speedy response. They went into my site via ftp and modified the mod so there were only 2 tabs - so I am very satisfied with the module and recommend their support team highly.
I expect they would be able to change the umber of slides to whichever you wanted, and hopefully in time it will be possible to do this via the back-end.
