Return error when try to activate

I’m sorry about this, it was a rushed-and-forgetten project >3 years ago. I understand your frustration with plugins you need that don’t work, I’ve been there myself.

Please note I’ve overhauled the plugin, completely rewrote it, and properly this time. It shouldn’t cause any headaches with failing the load (that’s unacceptable). As well the user interface is better, detection of an image has improved, option to exempt items added, and so on.
