The first part is where you upload the image which will become your icons in the Apple App Store and on respective iOS devices. All of your icons will be created from a single image. This image should be representative of your site and needs to be a 512 X 512 pixel PNG file with no transparency and saved as a single layer. You will need to create this image in the image editing program of your choice.

The next part is where you define your Splash Screen. This is the screen that the user sees the first time they open the App on their device and whenever they login to your site. You have two choices here. You can upload your own image to be used as the app screen or the Mobile Publisher can build one using your logo and the previously set colors.
