Crop auto-refresh thumbnails

I want to be able to have a thumbnail that is cropped to a certain spot, then auto-refresh this. It was an option available in an older speed dial extension that now no longer works. See it here: http://speeddial.uworks.net/

My suggestion is also a copy of this past suggestion, from 4 years ago: https://fvdmedia.userecho.com/communities/1/topics/2502-intelligent-thumbnail-editing
