It would be awesome if a photo contest with voting could be integrated to BP Media uploads. Ability to take groups galleries or all media an run a voting photo contest would be awesome integration to this plugin! Suggestion for a add on product or upgrade to BP Media.
We have previously come across this suggestion, as well. Currently, we are refactoring and revising BuddyPress Media to make it more flexible. After that we'll definitely consider this and update the status, here.
We have added "5-star rating" and "like" features inside rtMedia-PRO
Both can be used for voting.
Also, there are sidebar widgets and post-editor button to display "highest rated media" and/or "most liked media".
