Just a caution: Many "Free" images are likely actually scraped. I've learned to be careful. I usually use images from only a couple of places (including paid sources), because I really don't trust many "royalty-free" image sources. I have also taken to providing source links in the image captions.

One of the good things (maybe) about AI-generated images, is that you could generate an image that only exists for your article. The rub is that the generator may be giving you an image that is close enough to a copyrighted one, that you could still be sued.

I think that fonts could have the same problem.
