6 years ago In this page, there is a more complete example, that accounts for the cases when after optimisation the resulting file is not smaller that the original, non optimised one:

I have tried this plugin and it works properly. It's a nice add-on to the Pelican workflow. However, while testing for performance and optimisation, I have found that the resulting thumbnails are not fully optimised.
I know there are not a lot of Python options with regards to image processing, and I like the fact that this plugin does not require any weird dependency, but maybe there is something that could be done with PIL itself, like using the
qualityandoptimizeparameters, and/or making progressive JPGs (e.g.: https://stackoverflow.com/questions/6788398/how-to-save-progressive-jpeg-using-python-pil-1-1-7).
