footer image for sidebar widgets

good day everyone..

i started out with the movie-theme template…i have done some customizing to it to get it to do what i need it to do, however, am stuck on one thing

i am trying to get a footer image to show at the bottom of all the widget boxes that are put into the sidebars.

Is there a universal file that i can apply a <div> code to so it will add a footer tag, or do i need to go into each plugin and place in the <div> code?

thanks muchly
