Okay, let's kick this off by stating the obvious:
The first picture is Albert Einstein, famous for his theory of relativity.
The second is a physical map of France.
The third is of Prometheus, who in Greek mythology stole fire from the gods for mankind. The picture shows him tied to a rock where, as a punishment from Zeus, an eagle would eat his liver everyday before it grew back.
Finally, the fourth is a map of India, showing the different states/provinces.
As to what they have in common, I have no idea (yet).
