Using pictures in your slides does not mean that you are limited to using photographs from stock photo houses. You can certainly use your own camera — either a digital camera or even the camera built within your phone to source your own pictures. You can also look at some unconventional sources, such as a scanner. A scanner? Yes, that’s a device that several of us have not used for many years now — but if you have one of these devices attached to your computer, do consider it as a source of visual content.
