Presentations and lectures are improved by having interesting and engaging images in them – they make ideas and concepts more memorable and easier to understand. Provocative or humorous images can create a reaction and lift a presentation.
The challenge is to find good quality images that can be used without breaching copyright. Just because an image is easily accessible on the internet does not mean that it is in the public domain as far as copyright is concerned.
Fortunately there are a lot of images, and videos, licensed under Creative Commons licences. With these licences, copyright owners allow others to copy, distribute, and make some uses of their work – within the terms of the three levels of CC licences.
