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
