All matplotlib axes and subplots live in figures, you just may not
know it.  The call to gca in your code below:

  >>    ax = gca()
  >>    limx = ax.get_xlim()

automatically creates a figure and adds the axes to is.  So you can
still access the figure, eg

  fig = ax.figure

You can then call figimage

  # transform from axes coorrs (x,y) -> display coords (xo,yo)
  xo, yo = ax.transData.transform_point((x,y))
  fig.figimage(Z, xo, yo)

where Z is your image array
