URGENT: Need help debugging data upload module in applicatio

Hello Bidders, A client's application is not working properly and we need urgently someone to review and debug it. The application uploads jpegs, URLs and misc text data records and makes thumbnails of the jpegs. It can upload up to 600 of these from an admin panel. The problem is that the app right now will upload 1 jpeg and then not upload others. Uploading again deletes the records in the mysql database..so something is not working. NOTE: - PLEASE ONLY BID IF YOU CAN START IMMEDIATELY - Please bid quickly as i will select someone before project end - You must be an expert in PHP and should be able to understand other's code quickly Any questions, use PM please. Thanks, Sam..
