I agree, but most of the pictures look like stock photos or clipart. In my opinion, the first genuine photo are #16 and #19 (in my personalized order produced by Google image search, your numbers may vary). Anyway, the apparent genuine photos also have a good variation.

My complain is that most of them use white coats, so they look like Chemistry/Biology/Medical scientific. I never saw a Physics scientific with a white coat.

What should a physicist stock photo / clipart show?

That's probably a useful niche: stock photos and clip art that represent actual science.

Stock photos of real science is hard, it's easier to put someone standing at the side of the equipment they use in the real scientific work.

For experimental physics I like the photos of optical tables ( https://www.google.com/search?tbm=isch&q=optical+tables+lase... ) and the racks with a lot of electronic equipment ( https://www.google.com/search?tbm=isch&q=physics+laboratory+... skip the first 10 images). They look like something you may find in a real laboratory.

Theoretical physics is harder, they look like normal people (i.e. mathematicians) until they start to talk about the real word. I prefer to discuss writing in paper, but for a photograph the only sensible solution is to write a bunch of slightly related equations in a blackboard.

(And there are many other science branches. For Geology you may put someone with a bunch of rocks, but I don't know a real geologist so it may be not a representative image.)
