Modification on monstaFTP script

Hi, I am using MonstaFTP script which consist of 2 main files ([login to view URL]) to access FTP account via web browser I created a registration script to create 2 X FTP accounts for each user one account will carry personal files and the second account will carry share able files The owner of the FTP accounts will be able to copy/move files to the share folder from his main account this functionality is already there. What I want is like the following 1) The owner should not be able to delete his share folder 2) Only white listed users in owner list could access his share folder. (white list username is stored in sql db) 3) Other users can copy or download the content of share folder to their main account 4) View image button should appear for each image 5) icons represent file extension should be next each correspondence file, for example PDF file should show PDF .png image icon next to it.
