Spot on, Joel!
I used the Unsplash link until about a year ago when I was finally fed up with trying to find images that related to the non-mainstream subjects I write about. I got a Canva Pro subscription and now I digitally create my own images from scratch. It takes longer, but I get complete control and I feel much better about avoiding any potential snags with intellectual rights. Also, the continuity helps me create long-term branding.
Well done!
