QSL Cards

At the shack there are thousands of QSL cards stuffed into boxes. As an experiment I decided to see if there was a quick way of scanning these - so using a webcam to capture a still image, followed by a python script to stitch the 2 adjacent images together (as the front and back will be on 2 separate images) I managed 400 or so in a session.

stuffed up on flickr for now till I get round to finding a better place for em.

oh the script? it's my 1st adventure into the Python Imaging Library -- and its rather nice.
