Add frame to pictures system (experts only)

Hi there. I want to have a replica of the same system of this website: [login to view URL] There is a frame I will provide you, and mobile users will access the website, and be able to upload a picture and it will be added into that frame. Then they can download it or share it on social media. Check that website and test it on your mobiles for better clearance. It has to be done asap by today!
