[Answer]-Alternative of PIL/Pillow for using ImageField in Django Models

ImageField requires the Pillow library, see here: https://docs.djangoproject.com/en/dev/ref/models/fields/, no two ways around that. You will need to install it. There are several solutions in your case:

1. Install/get permission to run gcc on the server
2. Compile somewhere else, where the setup is identical and copy the files
3. Change your code to not use ImageField
