[R] image axes

I'm plotting matrices with image() and would like the axes to reflect
the conventional view that the upper left corner of the plot is (1,1).
But image seems to think that the lower left corner is (1,1). Can
someone suggest a way of persuading it to think otherwise. In effect,
I just want the y axis to run from from 1 to n downwards, not upwards.
I thought that something like axes=FALSE in image and
would do this, but the rev() effect gets lost for reasons I'm not too
clear about. Thanks for any suggestions...
