When submitting your app for registration, the app stores require you to also submit various image files to be used for marketing the product. Application icons will be used both in the stores and on devices when the product is downloaded. Follow the instructions as closely as possible, as we will not be able to finalize the registration without providing all required materials. You’ll likely need to coordinate the delivery of these assets with an individual familiar computer graphic tools, such as your departmental web coordinator.
