Example 5 on the demo uses our info slide script (hover over effect), are you looking for that or just plain images?
If you just want images it's the slide is just using standard <img> calls in a custom html module. That module is then published to one of the s5_tabX positions.
The way the tab show works is by publishing the actual module itself to whatever position you want. Then within the tab show there are slide positions, s5_tab1, s5_tab2, etc. Those are the slides of the tab show and where you would publish the custom html module above. In the tab show module configuration you simply pick which tab show positions you want to show in that particular copy of the module.
You can also download the Incline site shaper and install that in a sub directory if you would like to look at a live sample of the setup.
