How do I add an image for each menu column? I have 4 columns in the footer, and am displaying a different menu in each block(column). I would like to add an image above the menu items for 3 out of 4 menus. What is the best way to do this? Is it possible to add a field to the menu content type as such? If this was possible I could then create a view for each block/column, by pulling in the menu items and images...

What would be the best way to do this?
It's pretty easy to do that with CSS

#column-1{
  padding-top:20px; /* Space for image */
  background: transparent url('../images/bg-col-1.png') no-repeat left top;
}
