It’s amazing how generous people can be with their creations! Pixabay is a website which hosts and allows you to download high quality images that you can use and reuse any way you want! They don’t even require attribution, although that is always nice to mention. If your students are creating web pages or any other publishable materials, they may want to explore this site. The only caution is that you will also see “sponsored images” – they are clearly marked, have a watermark, and are NOT free, but they already went out of their way to make it very obvious, so there is really no confusing them!

And just a nice touch, you can always buy your favorite volunteer photographer a coffee (donate to the site).
I have written about using Google search to find copyright-free images in the past. Remember this blog is filled with invaluable tips, so set aside time to explore it!
