Thanks to Dr. Guy Le Masurier for providing us with these sheets!
Our Copyright Librarian Lori Walter has shared this excellent UBC resource. It includes links on how to cite images and LOTS of sites that have images you can use.
Lori specifically recommends these two sites:
Pixabay: Photos and clip art published under CC-Public Domain license (free of copyright restrictions). But note that sponsored Shutterstock images are also shown during searches but are NOT free of copyright restrictions. Those images are marked with a gray background and display the Shutterstock logo.
Unsplash: Free high-resolution stock photos depicting a wide variety of subjects. 10 new photos are released every 10 days. All photos are licensed under CC License Zero. Can be used for commercial purposes.
If you have any questions about image use in posters, presentations, and other types of publications please connect with VIU's copyright office, they would love to help you out.
