Probably the easiest solution would be to create a two image stack containing both the original and processed images. Here is a JavaScript example:

  imp = IJ.openImage("http://imagej.nih.gov/ij/images/boats.gif");
  imp.show();
  IJ.run("Set... ", "zoom=400");
  imp2 = imp.duplicate();
  IJ.run(imp2, "Find Edges", "slice");
  stack = imp.getStack();
  stack.addSlice("edges", imp2.getProcessor());
  imp.setStack(stack);
  imp.setSlice(2);
