Typically as slide shows controlled from buttons either inside or out of the MSO. That said sometimes these slide shows are considerably more elaborate than just having a stack of images. Often we might have a video on one 'slide' or each slide consists of multiple images each with their own animation which I assume we could achieve through Edge Animate integration.
The other most common way we use MSOs is to have multiple 2-state MSOs on a map, each with a blank 'null' state consisting of a rectangle without a stroke or fill and a state that has information like info pertaining to a chart or map. On these the states all have their null state as the initial state so upon loading none of the MSOs are showing. Then as spots on the map are rolled over the appropriate MSO switches to the information state and then back to the null state upon roll off.
