sized_picture is a very simple plugin for django-cms (https://github.com/divio/django-cms)
it adds the possibility to add fixed size pictures to your placeholders using sorl.thumbnail

Installation:

* copy sized_picture in you projects directory
* add it to your settings.INSTALLED_APPS
* also add sorl.thumbnail to settings.INSTALLED_APPS
* in your settings, set up the sizes choices this way:
SIZED_PICTURE_SIZES = (
   ('100x100', 'just an example'),
   ('200x400', 'another bigger example')
)
* you can also overide the default template with settings.SIZED_PICTURE_TEMPLATE
