images path and web services issue in clean url

Hello,

I am trying to implement clean url in my asp.net website.
when I try home all images are loaded properly, but if I pass parameter home/logout than images are not loaded properly. 
I am not able to call web services after implementing clean url.

This is the code I have written in mu global.asax

RouteTable.Routes.MapPageRoute("home", "home/{logout}", "~/default.aspx"); RouteTable.Routes.MapPageRoute("freeDelivery", "freeDelivery", "~/freeDelivery.aspx");
