I use an axis for preview the background image in background, i use an another to preview the image in a little box, but when i click "show image" the image rewrite my background image.

Sorry for my bad english, Regards, Hunor

Here is a code: function pushbutton10_Callback(hObject, eventdata, handles) axes(handles.axes1); global kep; global a; imshow(kep);

        function axes3_CreateFcn(hObject, eventdata, handles)
        backgroundImage = importdata('hatter.jpg');
        image(backgroundImage);
        axis off;

I have tested the following code and it works. Add it to your own.

% In the pushbutton3 callback
handles.output = hObject;
backgroundImage = importdata('background.jpg'); 
imshow(backgroundImage, 'Parent',handles.axesBackground);
axis off;
axis image;
guidata(hObject, handles);
% In the pushbutton5 callback
handles.output = hObject;
littleBoxImage = importdata('image.jpg'); 
imshow(littleBoxImage, 'Parent',handles.axesLittleBox); 
axis off;
axis image;
guidata(hObject, handles);

Defining the "parent" property allows you to choose in which axes you will display the image. I had used the axes(handles.myAxes) for plotting, not for image display, so I suppose that was the problem.

This should (finally!) work. Give it a try ;-) .
