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.
After some trust to the module will be gained, -Replace switch can be used, which will rename files instead of copying them.
