I am not sure if it applies but I think there is also an IDL object
called IDLgrImage that handles displays for large imagery (assuming
you are not wanting to display it all at once) and I think it only
loads as much of the image as required and thus reduces the memory
requirements. May also handle zoom type stuff as well.
