Download Photos from Instagram using API

I am looking to have small program created that has 3 parts - Find new instagram photos that have been geolocated or tagged with a specific tag. (e.g. @location and #tagthing) -downloaded images and place them into a local folder. - Take those images and display them in one of two ways chosen by user: 1. Grid pattern - 60 or so images on screen 2. Slideshow - 1 large image If Grid pattern is chosen, if image is selected a larger view of photo is shown and a print button appears. One 4"X6" pic will be printed to a Hiti 510 Dye sub printer directly. The software/script should run on a local computer (Hp Touchsmart 310 using Windows 7 Home Premium edition and be written so we can change the tags/location we are looking to pull and it should only download new images. If you have any questions please ask!
