Whenever I look at a pic taken from space, I can't help but notice the lack of stars. Can someone explain this phenomenon?

The stars are very feint, and the objects in the foreground of the pictures you are talking about are comparatively very bright. Cameras have a limited "dynamic range", that is a limited range of brightnesses that you can squeeze into the same picture. If the camera were adjusted to be able to see the stars, the other objects in the image would be a white blur.

You can try this yourself: Aim a camera at the moon and adjust the exposure until you can see the craters -- the stars should be gone. Then adjust the exposure until you can see the stars clearly -- the moon will be a single white smudge.
