Web Forms :: URL Routing - Images Stop Displaying When Page Is Routed

This is my last  thread [URL] .....

In details.aspx i have datalist that have 3 lable and 1 image when i write this code in global.aspx

 public static void RegisterRoutes(RouteCollection routes)
{
routes.Add("BikeSaleRoute", new Route
(
"bikes/{Data}",
new CustomRouteHandler("~/Details.aspx")
));
}

When i type behtob.com/bikes/1111 in addressbar it go to details.aspx and show this page with datalist that fill from my db 3 lables and 1 image but when i  write this code in my global.asax

public static void RegisterRoutes(RouteCollection routes)
{
routes.Add("BikeSaleRoute", new Route
(
"{Data}/",
new CustomRouteHandler("~/Details.aspx")
));
}

I should type behtob.com/1111 in address bar it go to details.asax but in my datalist just show 3labales that i bind from db it didn't show image that i bind from DB  what should i do? I want use second code.
