Creating a Windows Application to view Images

Question

Hi, I have images from a horse show that I was recently a part of and wanted to create a C# Windows Application that will allow me to do this. I wanted to put the images into a list box and but I wanted to pick them up from my images folder on the computer. I'm using VS 2010 and I've done some programming at school but just need a little help if anyone would be so kind? 

I remember that I have to use the directoryinfo object to pull the images from the folder but then i'm getting stuck. Could someone help me please?
