Add features to Wordpress NextGen Gallery Plug-in

I have a picture gallery on a wordpress blog. The picture gallery uses the Nextgen Plug-in. I would like to add functionality to the Nextgen Plug-in to: 1) Allow users to click a Vote button to increment a vote counter if they like the picture (a given IP can only vote once). Before they click on the Vote button, it shows the number of votes on the design so far. 2) Add share on social media buttons (facebook and twitter) for every picture, which then would post to that person's profile 3) Add a couple fields of info to each picture (probably by simply implementing the NextGen Custom Fields Plug-In. Allow one of the fields to be an html link. There are already other plug-in's you may be able to leverage such as Nextgen NextGen Custom Fields Plug-In: [login to view URL] NextGen Gallery Voting Plug-In: [login to view URL]
