Nice work.

If you want the images to fill the entire eDGe screen at full resolution, they need to be 1195x1024 pixels. The middle 600x1024 pixels will be visible in portrait mode (except the little bits at the top and bottom that are covered by the notification bar and nav bar). The side sections will be visible when you swipe left or right with your finger on the home screen.

"1024" is the screen's height in pixels. The reason for "1195" is that Android's wallpaper-choosing function requires you to crop any image to an aspect ratio that's approximately 1195:1024.
