Photograms, also known as Rayographs, are photographs that are taken without an actual camera by putting any objects on a light sensitive photographic paper and exposing it to natural light, for example the sun, for about five minutes. Wherever the object is on the surface of the paper, there will be a white or a pale grey colour in the shape of the objects left on the paper after you take the objects off. Without any objects on the paper, if exposed to the light, the paper will just turn completely black.
Photograms are also called Rayographs because a famous person named Man Ray named them after himself after "discovering" photograms.

These rayographs, as you can see, are very abstract images. In some of these examples of rayographs by Man Ray you can't tell what the objects within them are.
