Django ImageField that generates multiple renditions

Question

In the admin of my Django website I let admins upload images at a very high resolution. I want to automatically generate and store several renditions of each uploaded image at specific sizes, and then use the different sized renditions in different places on the website.

What is a good way to do this?

Answer 1

I ended up using django-imagekit.

Answer 2

You can use the image directly in your template and use sorl to generate the thumbnail or image at different size.

You can also override the model save method, check this small script:
