Description copied from interface: ImageArchive

ImageProd is a factory which produces PlanarImages - this returns a reference to the factory rather than the image to allow for easier background loading. Planarimage is defined in JAI (Java Advanced Imaging) it is a fairly high level abstract class and seems like the corect onr eo return from this method. Remote image is also a subclass of this so there is the posibility to do remote stuff also. This of course ties the system definitely to JAI. * @param alpha
