The rumor I've heard is that QlikView version 9 will let you email individual charts, and also that this is an extra feature that requires a higher license fee. I could easily be wrong about either part of this, though. I'm hardly a QV9 insider. Haven't even poked at it yet.
Edit: Another option, though outside of Publisher, would be to automatically dump images out of the QlikView. Rob Wunderlich has been working on that, and posted about it at the link below. I haven't played with the latest version of it, but I've been using an alpha version of his code, if you can call it that.
