I assume you want to do this in a function where you don't have the image array, otherwise it's a simple matter of calling axes() and imshow(), or use imshow() with the 'Parent' option. So see this first: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F to make sure you have the image array in the function you need it. Then call imshow(theImage, 'Parent', handles.newAxes).

You can also do something like

theImage = get(handles.oldAxes, 'CData');
axes(handles.newAxes);
imshow(theImage);

all in one function. Or try using getframe().
