Update a PHP WAMP Apache Access DB project

Our company provides scanning and indexing services. We have a web application that was provided by a developer who is no longer available. We have some information in the system and we need to be able to understand how it works and be able to maintain it or have someone do that for us. We are not PHP or Web Developers ourselves. The system is a WAMP server running PHP on Apache with an Access DB backend. The system is designed to allow multiple users to view scanned images and index them one at a time. The completed index data is then stored in an Access DB once the image and associated index data is submitted. Then the next image is displayed. The system is designed with multiple working folders that each user can select and lock. once they have "locked" it, then they are the only ones who can access and work on the images in that folder. The empty folders are manually re-populated by an administrator once all the images have been indexed and submitted. We can setup a GoToMeeting and show you the system and how it's used. We just don't know the backend design or how to administer it or make changes etc. If you are familiar and experienced working with PHP, WAMP, Apache and Access you should be able to easily figure out the system and be able to help us understand how to administer or change the system, or be able to do it for us. We would like to show you the system and let you go thru it and ask questions and research the various components and get familiar with it, then explain it to us and either give us some simple written instructions or we can record the GoToMeeting session to show us how to : 1. Change the Admin password 2. Add new files to the working folders 3. Locate the indexed images and related index data 4. Update the system if the IP address changes 5. Any other important information we need to know
