This section of the interface, entitled „General settings”, refers mainly to the dimensions of the show. You can modify them by inserting the desired number (of pixels) in the adjacent text boxes.
Two other options you can enable here are the shuffling and looping ones; in order to do that, just check the check-boxes adjacent to the corresponding text. Shuffle will arrange the slides in a random order, and loop will make your show start again - when its finished - in an endless cycle.
There are two buttons available for previewing your show. You can preview the entire show, from the beginning, by pressing the "Preview Slide Show" button, or you can select a specific element and click on the "Preview Slide" button - the preview will start with the slide where the selected element belongs (this option is very useful for large shows).
