How can I get the mouse position on an image after uploading it on axes

Hi,
I want to display the mouse position on my GUI. The problem is that it works on the axes. But after uploading the image it doesn't work any more. What is the problem? Or is there any other possibility to do it?
% --- Executes on mouse press over axes background.
function axes1_ButtonDownFcn(hObject, eventdata, handles)
% hObject handle to axes1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
c = get (gca, 'CurrentPoint');
x = c(1,1);
y = c(1,2);
set(handles.xPos, 'string', ['x loc:' num2str(x)]); % update text for x loc
set(handles.yPos, 'string', ['y loc:' num2str(y)]); % update text for y loc

By default Image objects capture mouse clicks. So if an Image is displayed in an axes, when you click on it it's the ButtonDownFcn of the Image that gets called, not the axes one.
%image creation using either imhsow, image, imagesc, whatever...
himage = imshow(something)
himage.HitTest = 'off'; %image won't capture mouse clicks, the axes will instead.
