Powershell Photo Organizer

I've started to organize all my photos from the last 20 or so years.

I found a powershell script to organize them into neat folders. However there were some problems with Swedish date format - so I made a minor edit and posted it to a github gist.

The original can be found here - many thanks jongio!
