# USAGE
#
# You need the s3cmd cli tool for this script to work, and make sure it works - http://s3tools.org/s3cmd
# type `s3cmd ls` and if you can see your buckets, you're ok
#
# the "img.dat" file that the while loop reads needs to just contain a list of http:// links to images
# e.g.
# http://example.com/imageOfCat.png
# http://example.com/photoOfASlipper.jpg
# http://example.com/pictureOfCatEnjoyingBeingInASlipper.pdf
#
# Holy Batman's spectacles - there's actually no reason why this has to be limited to images, 
# but I've named it now, so I'm not changing it. Should work for any file type
#
# oh actually sure, I've renamed it, that didn't take long at all.
