title: How can I reduce the file size of my iPython notebook?
body: <p>I have an IPython notebook which is several megabytes big although the code inside is just about 100 lines. I think it is that huge because I load several images inside.</p>
  
  <p>I would like to add this notebook to a git repository. However, I don't want to upload something that big which can easily be generated again.</p>
  
  <p>Is it possible to save just the code of an IPython notebook to reduce its size?</p>
