add functionality to custom iOS library (display image from server)

I have a small iOS library which detects the language code of the device, gets a text and link from a mysql database and displays an iOS alert message with the text and link from the database. I want to expand the functionality of the library and being able to display a fullscreen image as well: - add a switch in the database to decide wether to display an alert message (like it is now) or a fullscreen banner (new functionality) -> 0 = alert message; 1 = fullscreen banner - check in the app if it is iphone4, iphone5 or ipad and if the orientation is landscape or portrait - depending on the format which was detected, get a link from the database which is associated with an image file -> there will be 6 new columns for the URLs in the DB (iphone4_portrait, iphone4_landscape, iphone5_portrait, iphone5_landscape, ipad_portrait, ipad_landscape) - the image will be displayed when it is done downloading and will be cached locally. The ipad image should be stretched to retina size if it is a retina device. - add a "close button" to the fullscreen image to close it. The close button can be stored locally - when clicking the image it will take you to the URL from the database
