You can show these images as a slideshow at an event to generate interest and questions. You could also use the images if the students are supposed to be collecting points or stamps or something like that: You could ask them to tell you about some number of images or have them come up with a question about one.

These images are all cropped and sized to 1920×1080, so they fill most computer screens or high-resolution projectors. The file names are intended to be displayed along with the images, so I set up my slideshow program to do that. The order is not just random. I tried to put photos that would be recognizable to everyone every two or three images, and displaying it in alphabetical order will make that work correctly.
