Using images for widget titles

I am trying to use relative positioning to add a different image to each widget box as the widget title. We have made ribbons to act at the widget titles, but cannot place a different image into each widget box. We have tried using css to place different images into each widget title box using the widget title classes and ids, but apparently are doing something wrong. Right now we are using the left and left-inner side bars, the pages menu widget, and the text widget (which I may change to "recent posts" in the future). You can check out the site here at www.rmebuilders.com


Thanks in advance for any help you might be able to offer!
