To use this as is, create the following media types with no additional properties:
InternalMediaFolder - inherit from Folder
AppleTouchIcon - inherit from Image (assuming umbracoFile is a Image Cropper, not Upload!)
MicrosoftTileIcon - inherit from Image (assuming umbracoFile is a Image Cropper, not Upload!)
Allow AppleTouchIcon & MicrosoftTileIcon to be created under InternalMediaFolder
Create a "Internal" folder at root Media level and then create the Apple Touch Icon and Microsoft Tile Icons, either directly in the folder or organise how you like
