Is there anything out there in the PHP world with equivalent functionality to SORL thumbnail (a Django project).
Specifically: 1) It caches results (generating thumbnails on the fly is too cpu intensive). 2) It provides a smart cropping feature that crops to fit based on image entropy (so it doesn't just crop to center, but rather crops where the 'action' is).
The big feature I'm looking for is the smart cropping ability.
I found a drupal module from which I can lift some php code:

It's actually based on the same django-sorl-thumbnail approach cited, so that's perfect.
