Tip #3:  Use free images from Unsplash for your lectures and presentations

Over 3 million free high-resolution images are brought to you by the world’s most generous community of photographers.

Unsplash.com has a growing collection of high-quality images that anyone can use for any purpose. Unsplash “grants you an irrevocable, nonexclusive, worldwide copyright license to download, copy, modify, distribute, perform, and use photos from Unsplash for free, including for commercial purposes, without permission from or attributing the photographer or Unsplash.”

Creating an account with Unsplash is optional. I’ve been using the website for years and have never created an account. Downloading images is simple; you can choose from various sizes to fit your needs.

Current categories include Editorial, Experimental, 3D Renders, Architecture & Interiors, Fashion & Beauty, Current Events, Nature, Food & Drink, Film, People, Athletics, and Street Photography.
