You an accomplish this with the following code:

// Get the first background image
var bg = $(".div1").css("background-image");
// Assign a modified version to another DIV
$(".div2").css("background-image", bg.replace(".jpg", "_highlighted.jpg"));

Whether or not the following is applicable to your project, you decide: I would like to point out this type of stuff is generally best handled with classes, and using jQuery methods like:

$(".div2").addClass("highlighted");
$(".div2").removeClass("highlighted");

It greatly reduces the verbosity of your scripts, and allows you to keep visual styles maintained in your CSS, rather than being partially-dependent upon values and strings within scripts.

Close but replace returns a string, it doesn't change the source.

I think you want this instead:

var div2bg = $('.div1').css('background-image');

$('.div2').css("background-image", div2bg.replace(".jpg", "_highlighted.jpg"));
