Next: How do I change the axes on an image?

Hi,
I'm a student of Computer Engineering at 'La Sapienza' university in Rome and i'm development a GUI for visualization of mri images.
I have six axes in which are displayed the images.Particularly in every axes is displayed a projection of every image.
The images are displayed by using the imagesc command(so the images are in the form of data matrix).
i'm need to define a synchronized pointer(crosshair) that, by clicking in one of this axes(and so selecting a point in one of the projection of the image), shows the corresponding point on all the other axes(projection).
Thus, I need to understand how can i draw a point(circle,point,...) on an image.
Can someone help me?
Thanks a lot.
Best regards,
Luigi Pavone
