Need paste of JPG etc

In a separate thread we're talking about using a Tablet PC. Pasting a copied drawing, in JPG format, would be almost as good. I could navigate thru the Prezi, come to some place where I want to draw, when switch to my drawing tool, Journal or SketchBook or whatever. When done drawing, I could optionally copy the image in Journal, paste into Prezi, and even link it in at that point. Way cool.
