Hi @pdehaye,

this is probably not the cleanest way to do it but it works: I generate and modify the `jupyter_notebook_config.py` file locally and upload it to Github. Then in `postBuild` I just copy that file to the right place. With that I manage to upload images of a few tens of Mb in the Binder session. Above that, uploading stalls.

You can find an example here: [https://github.com/guiwitz/voila\_image\_processing/tree/master/](https://github.com/guiwitz/voila_image_processing/tree/master/)  
In this example, if you click on the Binder badge it will open a Voilà dashboard ([https://github.com/voila-dashboards/voila](https://github.com/voila-dashboards/voila)) that works with ipywidgets. If you want a regular Jupyter session you can just take the regular route via the [mybinder.org](http://mybinder.org) site.

I hope that helps!
