Client Area Improvements, Admin zone and client zone front end. -- 2

I have a private zone ready made with PHP, javascript and html. I can create users and edit them. For each user its possible upload files: fotos, docs.... and I can create categories and subcategories for each client. I have a client zone frontend, where clients can see yours documents. (see attached client area frontend) All this works ok. the problems are: I can not upload multiple fotos at the same time, Now is 1 by 1. I need a system drag and drop or similar to Select multiple photos at once. After uplodad, I need can change the title for each. And need create the thumb too. See attached Admin area. The other problem is that I need upload video files and now I can not. There are an option bust just let add a youtube id, I need file upload for all types of video (the on client area is just download link). All the uploaded files now are online when user login, (see attached client area frontend) The new features should be available too in the suer area. Then you need I will accept offers in 3hours aprox, And I need all ready next 2th August.
