Have you considered using the optional arguments to imagesc() to specify the
positions of the corners of the images?
imagesc([1000 3000], [2000 4000], a)
would put the lower left corner at axes coordinates [1000, 2000] and would put
the upper right corner at axes coordinates [3000 4000]. (Not actually the
corners themselves, but for the precise details look at the documentation for
image() )
