Use the annotation command. I think it will work if you use it on the figure, and not on a particular image axes that your images live in. This is because I think if you use it within a particular axes, I think the arrow will be clipped when it would extend beyond that axes. The tricky part is that you have to figure out what figure coordinate corresponds to a particular location inside the axes. Like row 30, column 42 in your image corresponds to coordinate (543, 753) of your figure. But I think you need to do this if you want to have your arrow go from a pixel in one image, across blank space in the figure, to some pixel in the other image.
