Hot or Not needs modification

I have a social network site with a hot/not feature where you can vote on profile pictures. For my site members can have one real life profile and as many character profiles they want. Currently the system adds all pictures to the hot/not page. Currently the system is not putting the correct pictures in the top 25 according to their rating. I want the hot/not page to ONLY show the Main profile picture for the real life profile and the Main profile picture for each character profile. I want it so a member can only vote on the same picture ONCE and they cannot vote on their own picture. If they ever change their main profile picture for real life or for character profile they should have their score reset back to no votes. Also on the profile pages is a button for "Rank user" I want this link to go to the hot/not picture for that profile they are on.
