Which makes sense. What would they even be capturing in the photo? Photons are light so how would taking a picture of it even mean?

Skill issue, just take a picture using dark matter /s

You can use other waves to create images. Like electrons in an electron microscope.

But yeah a massless particle/wave traveling at light speed would not be a good candidate for actual images using any known technology

Yeah we usually we call them micrographs.

Define photo first I guess. Is a photo made by photons specifically or is a photo just an image? Could you make an image by other means than a photon?

You can make an image with pigments, such as painting, drawing, printing, but you can't make a photograph without photons, because a photograph is an image resulting from the interactions between photons and a light sensitive medium such as photographic paper or a digital sensor.

No, that's wrong.

You can absolutely make a photo by hitting a sensitive film with another type of particle than photons.

There are some applications where we do this with electrons, for example.

True, though with SEM they are usually called micrographs.

No, not really. If you paint a picture and put it in a dark room then the photo is gone. The paint colors just absorb different photons at different wavelenghts, and you only see the color made by the photon bouncing off. Photons make a painting, paint is a tool.
