Dave has released CoverMii v0.3 a pc-tool, which can download cover and disk images based on their Game-IDs. It is coded with visual basic and needs a .NET Framework.
It can download every 3D and 2D cover from each game region and also cover that are not found by USB-Loader GX.
CoverMii is current in two different languages available, in english and in german.
Here is the current changelog (translated by me)

To change its language to english, you must go to "Einstellungen" and then klick on "Sprache". There you can choose "english"
