[feature request] Note image and autorename.

[panwanke]

I notice that it.annotation can export images but the it.notes doesn't seem to be able to.

So I'd like to be able to include images in the it.notes as well, which seems to be possible in bibnotes fronmatter.

Also, it would be nice to know how you can rename images automatically, especially if you can set a custom path when custom naming.

Thanks to the developer very excellent plugin, great efficiency boost for my workflow as well.
