will give you information on getting the image names. Once you have them in a cell string array, you can set() the listbox String property to that cell string array.

In the callback for the listbox,

choices = get(hObject, 'String');
selected = get(hObject, 'Value');
thischoice = choices{selected};

my_pngs = dir('*.png'); % choose png files from directory
pics_cell = cell(numel(my_pngs),1);
for k=1:numel(my_pngs)
    pics_cell{k} = my_pngs(k).name;
end
set(handles.my_list,'String',pics_cell) % my_list is the name of your listbox

i put this in listbox_callback

It does not go in the listbox callback, it goes in the place you want to trigger the initialization of the listbox.

David, more efficient:

my_pngs = dir('*.png');
pics_cell = {my_pngs.name};
set(handles.my_list, 'String', pics_cell);

yes it's done iput a pushbuton to initialise the listbox the problem now is in set(handles.my_list, 'String', pics_cell); it show only one image in the listbox how can show all the images

[malek el pikho]
