Storyline 2 has a terrific interaction that allows me to create image sliders quickly any easily. While this is a fairly simple example of how an image slider can be used in a course, one of the nice features of this slider is that the slider can be reset ie. the learner can drag the slider in either direction to review the content presented as desired.
This interaction could work for a variety of content. Interactions could also be developed which have full screen images.
