For what it's worth, Compass already provides a similar feature. It's called image_url() and it will use your project's image directory as a relative root.
http://github.com/chriseppstein/compass/blob/master/lib/compass/sass_extensions/functions/urls.rb#L36 Even if you don't decide to use compass, you can see how it works by reading the code. You call it like this: div background-image= image_url("foo.png") and it emits (assuming your configuration has images at /images): div { background-image: url(/images/foo.png?12345678); } The query parameter is a cache buster in case the image changes -- it can be disabled if you don't want one.
