When building a Windows Metro (aka Windows 8) application it is important that your application have a nice looking tile.  It is also encouraged to enable your tile to be ‘live’, meaning it can update itself with content based on some event, if that is relevant to your application.  When you create your tile you can decide to have either a small tile which is 150px x 150px (this takes up one column in the UI) or to have a large tile which is 310px x 150px (this takes up 2 horizontal columns in the UI).  It is up to you to decide if you to support only the small, only the large or both.  Fortunately for you associating the images used could not be simpler.

1. Open the Package.appxmanifest
2. Open the Application UI tab
3. Provide an image in the correct logo box
   
   

If you only provide a small logo you will only have that option on the Start screen.  If you only provide a wide logo that will be the one which is used.  If you provide both, the wide will be used by default, but the user can switch to the small if they want.

Here are the logo’ used in the image above (remember I am NOT a graphic designer )

Small:

Wide:
