But, i can share my thoughts about the issue you are having. As far as i know, it is not quite easy to include product picture in the minicart (since the minicart is updated by AJAX update).
I remember i have tried it before, but then i gave up. Ask it in forum.virtuemart.net, maybe someone come up with a solution.
