Awesome! Going to give this a try tomorrow. Sorry I haven't been merging requests, been crazy busy!

You should consider to add the cropping direction to the file name too, to ensure that it is updated if the cropping direction has changed on the image.

-> image-300x200.jpg

to

-> image-300x200-tl.jpg

Otherwise the image is not recreated.

Cheers
