Is this plugin free?

Yes.

I do plan on charging for additional features later, but the core function will remain free for now. Even if I start charging for all usage, then existing users will remain free for the current range of features.

So if you install the plugin and register now, you’ll get the current functionality free, always.

I do ask you to register first however. This is so I can monitor usage – how many images you generate over time. And that will give me an idea of what to charge new customers in future.

You can register for free here.
