Great! Couple follow-up questions:
1. If admin creates a post (a general website post, not specific to a user or group), would these images go to the same database or will I have two separate media database?
2. if a user wants to add an image that would be associated with a post that was created by the admin on the back end (i.e. it is not a they did in their group or profile), would they be able to do that?
