Can you prove that a screenshot is real?

Is it possible to prove that a screen shot of
a)a facebook PM
b)a facebook chat log

are real?

and not edited/manipulated with some graphic program..?

thanks!

Not easily. A forensic scientist might be able to; but they'd ask to pull records from the original server where the content resides, or from their official backups.

too bad :-( thanks for the reply, though!
