Copyright-Free Images
As an art teacher, I have been collecting websites that provide good-quality copyright-free images for many years. Please note that copyright-free means that you don't have to pay or ask to use certain pictures but you should still give credit to the photographer. Some sites have Creative Commons licenses and those should be attributed as requested. Here is an excellent article about what permissions you need to have: https://www.cultofpedagogy.com/online-images/
I also want to warn you about a potential scam where someone insists that you are using images that aren't copyright-free and insists that you link to their website. The payoff for them is that the more pages link to a site, the more potential for moving up in Google ranking or other benefits. So if you get a letter about this, follow the advice in the link.
