How to upload image files to ipython notebook for further image processing
Question: Instead of working with generated plots and graphs I want to use existing
pictures to perform image processing on them. In
[`sage`](http://www.sagemath.org/) one writes:

    
    
    from pylab import imread
    image = imread(DATA+"image.png")
    

The [official help introduction](http://ipython.org/ipython-
doc/dev/interactive/htmlnotebook.html) is silent regarding this task / use-
case / problem.


Answer: After googleing and trying for 30 mins, I found out, that is actually quite
simple.

The notebook has file access to the folder it was launched from. So if one
started it in one's `home` folder one can access all the files from the `home`
folder directly.

    
    
    from pylab import imread
    image = imread("image.png")
