Possible to get an example of how to set controlnet image with PIL?

I've been trying to get the individual controlnet "Loopback" toggle to work through your controlnet implimentation, but haven't been able to.

I saw in your recent notes that you've allowed fro setting a controlnet image with PIL. I was wondering if it's possible already to set the last generated image as the input with this. If this is possible already, could explain more or give an example? I've been using loopback script and loopback scalar script a lot lately, and they are really powerful. It would be great if I could access a last generated image via global variable or something, and then input that to the next img2img generation step during the loopback cycle that rather than only having the option to input an on disk image.
