Small Android app

I need a very small database app with a web based admin panel. I need an app in which i can collect and store my image database under different categories for eg:- chairs, beds etc. This will be useful for anyone who wants to browse through a couple of designs. Admin Panel:- Web based Should be able to add categories should be able to add images into categories PS:- See attached image - This is how the look should be - I want to capture everyones email - also when a person clicks on an image it should become full screen and even the categories will be showed in this way only with a pic and some title text So this is how the structure will be 1st Screen - Enter email 2nd screen - Category Images ( Eg, Bed, Lamps etc) 3rd Screen - A person clicks on a category and gets access to those images Admin Panel - admin can add/edit/delete categories and category images.
