I've been able to be successful with autoFillImageProperties (as outlined here: https://our.umbraco.org/documentation/reference/config/umbracosettings/) if I create a new media type... but I cannot figure out how to get this to work if I have an ImageCropper preoperty added to a custom document type.

Has anyone ever been able to get this to work in a custom document type? if so, I'd be much appreciated if you shared how you got it to work!

Thanks!
