Not every presentation slide needs an image
Yes, visual slides with stunning images are more powerful than boring lists of long bullet points. But that does not mean that designing good presentations is the equivalent of finding a stunning image for every page (sorry).
- A powerful quote can look beautiful on its own, in naked typography. The image of the person might distract the audience, especially if it is a relatively unknown author of an airport book best seller.
- A simple information slide (here are the 3 priorities for next year), but just be best visualised with a simple list of 3 priorities.
- Section breaks can be done in 2 ways: a dramatic visual to show the transition, or an almost blank page that brings the attention of the audience back to you
- It is very hard to find dozens of images that are more or less similar in style or look and feel. As a result, presentations with lots of images look inconsistent.
It does require though that you find a way to make a typography-only slide look good. A nice full colour plain background, and some elegant stealing from the Swiss graphics design masters in the 1960s is a good way to start.
