Django-wiki uses the [PIL library](http://www.pythonware.com/products/pil/) for image processing. If you plan to enable images on your wiki, you'll need to make sure you have libpng and libjpeg installed *before* beginning the pip install process. If you don't, you'll see the IOError exception popping up when a user uploads an image. The library installs are platform-specific, here are notes for installation:
Django-wiki uses the [PIL library](http://www.pythonware.com/products/pil/) for image processing. The preferred method should be to get a system-wide version of PIL, for instance by getting the binaries from your Linux distribution repos.
**Ubuntu/Apt-based Linux Distros**
**PIL Directly from repository: Debian-based Linux Distros**
sudo apt-get install python-imaging
sudo apt-get install python-imaging
**PIL/Pillow for Pypi**
Firstly, you need to get development libraries that PIP needs before compiling. For instance on Debian/Ubuntu:
After that, choose either `pip install PIL` or `pip install Pillow`. Pillow is the pip-friendly version of PIL. You might as well install PIL system-wide, because there are little version-specific dependencies in Django applications when it comes to PIL.
