Module extracts date and time from picture and change name of the picture to it. It uses format yyyy.MM.dd_hh.mm (2013.08.30_13.08.31).
Module allows to use -Recurse switch. By default it creates directory at the same level as working directory with images which have new name.
If two photos had been performed in the same second, module will append suffix _0 _1,....
Set-PhotographNameAsDateTimeTaken -Recurse -Verbose
After some trust to the module will be gained, -Replace switch can be used, which will rename files instead of copying them.
