Differences referencing image from localhost and server

[eluser]Unknown[/eluser]
Thanks for replying, but I don't understand.

I'm referencing the image in a <div> like this:

Code:

background-image: url('/images/splash-logo.jpg');

If I use the '/' at the beginning it will display on the server, but not on my localhost.

If I don't use the '/' at the beginning it will display on my localhost, but not on the server.
