You  just load home this page
and open the sourcecode in Dos_edit or Notepad                                         names are_ _ 1.gif _ 1a.gif

 

  As you can see there are two nice images                                                    and    _ _ 2.gif & _ 2a.gif
when you move thy pointer over them they will change.
 

Just make (: Loan? :) your own giffs & then name them the same as mine ..
you'll get the best effect if you keep the giff:s the same size..
And remember to give an URL page for people to go...
