loading multiple files simultaneously to GUI axes

i used these codes hat i've got from the web to load files one at each time upon clicking the push button. but how do i load them by selecting 4 files and load them simultaneously in the GUI axes.

[nombre dire]=uigetfile('*.jpg','Load');

if nombre == 0

   return
  end
  imagen=imread(fullfile(dire,nombre));
  axes(handles.axes2)
  imshow(imagen)
  handles.img=imagen;
  guidata(hObject, handles);
