How do I create a slide show ?
Slide shows can be created via the Window -> Interactive -> Object States palette. To create a multi-state object, place a number of images in your document and align them in a stack. then select them all, and click the "New" button in the Object States panel to create a multi-state object. You can also change the order of the images in the slide show.
In the iPad app, a user will be able to go through the slide show via swiping (if you have enabled user interaction).
You can also provide a full-screen slide show. The full-screen slide show will be available by double-tapping the picture. Keep in mind that if you want to provide a full screen slide show, the images should be available at a full screen resolution, i.e. more or less 132 ppi at a 1024 x 768 resolution.
All slide show options will become available in the Twixl Publisher palette when you select a multi-state object. More details are available in the Twixl Publisher palette section.

After you have created a multi-state object, all interactive
options that are relevant for the iPad can be accessed from the
Twixl Publisher palette.

Export
If you are using transparency in your slide shows, then use 'PNG'.
Otherwise you can export as 'JPG'.
Appearance options
"Show Scroll Bars": show scroll bars at the bottom of your
multi-state object.
"Show Scroll View Indicators": shows iTunes-like page indicators -
i.e. when you select this option a semi-transparent layer will be
added at the bottom of your slide show to indicate the number of
pictures. You can control the look of this layer by selecting the
background color and its opacity, as well as the active and
inactive page colors.
Behavior options
"Allow User Interaction": controls whether a user can scroll
through the slide show
"Allow Full Screen View": double-tapping a slide show toggles a
full-screen view of your slide show
