Arrange Images as per their timestamps

.gitignore

*.pyc

README.md

###Project A small script to arrange the images in the present folders and subfolders as per their time of capture. This would help easing their uploading to google plus photos, making a clean ordered library along the way.

Due to some blunder my images have been shuffled during import and I'd like them to be in order.

###Dependencies

1. Python 2.7
2. Python Imaging Library
