How to open image directory in matlab GUI and processed using external functions?

hi, i have a question regarding matlab GUI. how can i open the image directory and then use the image throughout the whole GUI? i have external functions for the segmentation process but the image displayed seems to be outside of the axes.

    % --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

global im FileName
axes(handles.axes1);
[im,PathName] = uigetfile('*.jpg','Select the MATLAB code file');
FileName=im;
imshow(FileName);
% SelectFile=funGetpushbutton1(hObject, eventdata, handles);

% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global im FileName
FileName=im
b=badrulsegmentation (FileName);
axes(handles.axes1);

as you can see above, my function (badrulsegmentation) is my function for segmentation process. when it comes to the function, all the images were displayed outside of the axes. where did i do wrong? please help me

pushbutton1 will display the chosen image in axes1. Where does pushbutton2 callback and the badrulsegmentation() function display it? When you say "all the images were displayed outside of the axes" then where were they?

sorry, missed out the imshow. but still, the images were displayed outside of the axes. they were displayed just like a normal script. meaning like the multiple figures when using script. image in axes1 remained the same and only that image is inside axes1. Is it because in my segmentation function,i just use figure(1),imshow... and did not declare axes1 in the function
