From the developer:
Superoverlay software is a Google Earth application for tiling raster datasets and creating view based regions in KML or KMZ files.
Also Superoverlay can generate world files for all images in ArcView style (jgw, tfw,...). It helps you put large image overlays into Google Earth (for example alternative maps or aerial photography). GE Sky mode is supported.
You may want to check out more software, such as Poster Buddy, Your Birthday News or peopleputty, which might be similar to SuperOverlay.
