The mm_exif module provides the ability to search through media files (jpeg so far) finds the Exif data and removes it. Removing Exif data protects user's privacy. Allowing a user to upload sensitive material without allowing others to use the uploaded file as a way to track down that user.
mm_exif module relies on jhead to find and remove the Exif data.
Download and install jhead on your server first: http://www.sentex.net/~mwandel/jhead/
