URGENT: Fix issue on android/ios app

Hello. We got a application for android and ios. Its a application for our web-radio. What you have to do is at the main page, the application should be able to fetch the cover image of the song being played at each time. We got the files and the php files of where the cover images are taken from (amazon). File is here: [login to view URL] PHP files are attached. If they are not applicable, i can give you the amazon logins to check by yourself.. project is realy urgent. do not bid if the amount of money that you ask is over 50$ thanks.
