link manager

Im looking for a php script that manages links and images submitted by users. The script needs to be able to do the following: - accept link and images submission into a database - verify links for errors - ban IP\'s from submitting - rotate links - verify the email of the submitter - generate the links into html(templates) - crop images submitted - upload images to server - be able to manipulate SQL database. updating and deletion etc - able to export database to textfile and import data from text file. these are just the major features of this script. there are other minor details but they can be discussed.
