Presentation Software

It seems most if not all speakers use or will eventually use presentation software (such as PowerPoint) to engage their audiences.

While building our signature talk, should we or should we not plan on using slides or pictures for effect or summarization of information.

It's often a crutch for many but can be a powerful ally if used correctly. Your thoughts would help to streamline the content and direction of our signature talks concerning this. Thank you so much ahead of time.
