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

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);
