You do realize this post is completely incomprehensible, right? Only by clicking the link is it possible to discern what the heck you're even talking about; it turns out to be some iOS- or possibly iOS-and-Mac-specific software providing access to a desktop wallpaper gallery, of which the least interesting is probably the one you selected for your photo. I'm utterly baffled by this post: I can't tell why you care (why almost anyone should care, as the whole point of your desktop wallpaper is to cover it with active windows), nor what you intended your readers to discern.
