Matlab GUI - Display image selected in popupmenu to axes

I need to display the image in an axes which i selected in popup menu. I am generating the popup menu list dynamically by using the following code:

function popupmenu1_Callback(hObject, eventdata, handles)

DirEntries = dir('C:\Users\User\Desktop\Project\Images'); uicontrol('Style','popup', 'String', {DirEntries.name});

Now which ever image that i select in this pop up menu should be displayed in 'axes'

Can anyone help me on how to display the selected image in the GUI

This code should do the job

function script
figure;
directory = 'C:\Users\User\Desktop\Project\Images';
Dir = dir(directory);

axes;
h = uicontrol('Style','popup', 'String', {Dir.name}, 'Callback', @popupmenu1_Callback);
setappdata(h,'Dir', directory);



function popupmenu1_Callback(hObject, eventdata, handles)
value = get(hObject, 'Value');
directory = getappdata(hObject, 'Dir');
images = get(hObject, 'String');
% Do a check if this is a valid image
imshow(strcat(directory,'/', images{value}));
