Note: The reason why most of us are using this version of a Image Size Regenerator is, that its so straigh-forward. I tested quite a few different variations by other authors, including the oh-so-famous wp-cli variation, but non worked as reliable as the original.

I've been very happy with its performance so far, installing whenever there is a need for custom-sized images in a project of a client, and been recommending it ever since I first stumbled upoon it.

The only grieve I got is that there seems to be no way of "cron-jacking" the plugin. No, the wp-cli variation is much too complicated. Not everyone - or more like, most of the rest of the world - does have a server to themselves. And setting up the "remote" version is a PITA and huge struggle as well. So one has to stick to the GUI version of the original plugin .. for now.
