Is there a way to have different membership packages to allow a different number of posted pictures?
For instance, 2 pics, 4 pics, or 6 pics respectively?
There is no feature on this currently but it is possible through custom coding. Since the theme is not encrypted it can be modified accordingly and of which implementation is just dependent upon your programming skills or you can just hire a coder to do it for you. Appthemes also have certified community partners http://www.appthemes.com/partners/ that can be contacted for customization jobs.
