If using images from the Internet, ensure that you are following copyright laws. For more on copyright, read this helpful guide on Finding Images.

Ensure that your slides are accessible to all audience members. The University of Guelph, Office of Diversity and Human Rights has several resources to help you make your slides or other presentation materials accessible.
