YES!! I did it, was a little tricky with all those classes and
sub-classes but this did the trick:
RenderedOp ro = (RenderedOp) grid.getRenderedImage();
PlanarImage planarImage = ro.getCurrentRendering();
ImageReader reader = (ImageReader)
planarImage.getProperty("JAI.ImageReader");
FileImageInputStreamExtImpl input =
(FileImageInputStreamExtImpl) reader.getInput();
