right so i have an image that i have we will say its ____________________________________ long.. but i want the roller over for when people click or roll over it to be ____ long how can i do this for a horizontal navigation bar without slaughtering the large image.. would it work to put the base one as a background layer, but then put an invisible roll over layer on top that will work as the button? otherwise if thats not going to work.. anyone have a dirty/ rustic / rocky and dark looking navigation bar?
