[IPython-User] PIL Display Hooks

It should definitely be possible to do this.  Here is what I would advise:

* Look into generating raw JPEG/PNG data from an image.  You could
write this to a file and then read it back in, or possible write
straight to a python bytes object.
* Then look into IPython's display protocol.  The best resource on
this is the display_protocol.ipynb example notebook in

Once you have the raw JPEG, it shouldn't be more than a few lines of
code to hook into the IPython display system.  Once that is done
images will "just work" in the Notebook.
