JQuery changing img source

So I want to make a changing image gallery where the images change ever few seconds, so I tried to butcher someone else reference code and its not working. Can someone explain why. Here is what I put

$(function () {
    var backgrounds = [
      'url(../img/G1.jpg)',
      'url(../img/G2.jpg)',
      'url(../img/G3.jpg)',
      'url(../img/G4.jpg)'];
    var current = 0;

    function nextBackground() {
        $(".indiesI").attr(
            "src",
        backgrounds[current = ++current % backgrounds.length]);

        setTimeout(nextBackground, 5000);
    }
    setTimeout(nextBackground, 5000);
    $(".indiesI").attr("src", backgrounds[0]);
});

Hi Daniel,

I added markdown to help make the code more readable. If you're curious about how to add markdown like this on your own, checkout this thread on posting code to the forum . Also, there is a link at the bottom called Markdown Cheatsheet that gives a brief overview of how to add markdown to your posts.

Cheers!

Hi Daniel,

With jQuery you dont have to specify 'url()' when you are changing the src attribute, so if you remove the url() it will work

var backgrounds = [
      '../img/G1.jpg',
      '../img/G2.jpg',
      '../img/G3.jpg',
      '../img/G4.jpg'];
