This was post was duplicated in the forums. The duplicate: https://community.tableau.com/message/853891 was removed so that all the resources available in the Community Forums can collaborated in a single location.
I was also able to find this blog that might have a potential workaround for achieving the desired result.
Subscribing users to a view can also be an effective way of disseminating a Tableau Dashboard image: Subscribe to Views - Tableau
Hope these suggestions help!
