Yeah, many of those older photos I reused from my original classes back in 2002. However, some of them I sourced from the Internet, such as that classic color computer photo. It's quite surprising, but a significant portion of the photos were actually generated using AI through Leonardo. I find this process fascinating. I can simply describe the kind of image I need, like an elderly person looking puzzled at a computer, and Leonardo creates the image accordingly. The best part is that all these images are royalty-free, eliminating any concerns about using someone else's pictures without permission.
