Approve or Reject Uploaded Avatars for Jomsocial

I need to be able to approve or reject uploaded avatars for the Joomla script Jomsocial. I would like this to be separate from the Jomsocial script so it would work with future upgrades. I'm looking for a quick and dirty solution, nothing fancy. It just needs to be functional. If it helps, the avatars are uploaded to a separate directory inside the root folder of Joomla, in images/avatar/ Please send me an idea with possible ideas. I'll try to answer questions you may have. My budget from this project is preferably around 50 bucks.
