Hi, Usama.

Maybe you are seeking for something like this?

In the openingfcn

function untitled_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
files = dir(fullfile(pwd,'Folder01','*.png'));
for x = 1 : length(files)
    handles.images{x} = imread(fullfile(pwd,'Folder01',files(x).name));
end
set(handles.listbox1,'string',{files.name});
guidata(hObject, handles);

In the listbox1 callback

function listbox1_Callback(hObject, eventdata, handles)
handles.output = hObject;
index = get(handles.listbox1,'value');
imshow(handles.images{index});
guidata(hObject, handles);

You can also change the image extention by replacing png with another extention

Eq: files = dir(fullfile(pwd,'Folder01','*.jpg'));

And if it is DICOM files

files = dir(fullfile(pwd,'Folder01','*.dcm'));
for x = 1 : length(files)
    handles.images{x} = dicomread(fullfile(pwd,'Folder01',files(x).name));
end

I hope this helps.
