[OSC] Personalization of Admin Manufacturer.php

I need a modification in the file manufacturers.php. This file is used to manage Manufactures info, to wich we added some filed and now i'd like to extend the personalization adding some other filed uset on the front end shop to make up a slider. This new functionality is a slider with images that the customer will see on the Front End when they choose a particular Manufacturer. So i need to manage a list of images and file upload, all driven by DB. I need to upload image, delete image, sort the list to decide what to show and in wich order. On top of that every image should have a 'link' paired with it. All should be DB driven, of course. You can see and example of the Slider here: [login to view URL] For the sort i want this: [login to view URL] For the Upload this one would be nice: [login to view URL] So, Adding file and link, Removing unwanted ones and sort them (with thumbnail), all of this in the same form used to modify the property of the manufacturers. I've attacched a simple Pics mokups of where it should be placed.
