I'm redeveloping this site for a non-profit.
There are problems with the following site:
http://www.capodevelopment.com/gngproject/www/

How can I mimic the tv in the bottom right using only jquery?

Right now I've already preloaded the images, and I have them in an array.

I just don't know how to make a function that will put a small, but random delay between changing the image.

There's a div element, whose background image is the tv picture.
So in the code, I need to change the image like:
$('#homeTvSlides').css('background','img/img1.jpg');
-except, on a delay.

What about something like this.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>TV with JQuery</title>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
    <script type="text/javascript">
        var fuzzy1 = "http://www.wallpapersbay.com/wallpapers/fuzzy_screen_png-1024x1024.jpg"
        var fuzzy2 = "http://www.testplant.com/phpBB2/files/vnc_fuzzy_screen.jpg"
        var imageArray = [{ img: "http://i45.photobucket.com/albums/f96/thirty7blinks/beaches_winter_sidewalk_reflection_.jpg" },
                          { img: "http://i777.photobucket.com/albums/yy57/Freethey/winter001.jpg" },
                          { img: "http://i261.photobucket.com/albums/ii41/Thumper460/WinterSnow.jpg" }
                          ];
        var imginterval;
        var imageCount = imageArray.length;
        var currentImage = -1;

        $(document).ready(function () {
            //set the initial image to be fuzzy
            setImageSrc(fuzzy1);

            //kick off the interval to run every 5 seconds
            setInterval(transitionImage, 5000);

        });


        //function called by the interval
        function transitionImage() {
            //if you have reached the end of your image list, cycle back to the first
            //the trick here is to remember that the length of an array is 1-rooted, and the index of the items is zero-rooted
            if (currentImage + 1 > imageCount - 1) { currentImage = -1 };

            //increment to the next image in the imageArray
            currentImage += 1;

            //flip back to fuzzy
            setImageSrc(fuzzy1);

            //wait 1/2 second to flip to the second fuzzy
            setTimeout(function () { setImageSrc(fuzzy2) }, 500);

            //finally - set the final
            setTimeout(function () { setImageSrc(imageArray[currentImage].img) }, 1000);


        }

        function setImageSrc(src) {
            $("#screen").attr("src", src);
        };


    </script>
    <style>

    </style>
</head>
<body>
    
   <div class="tv" style="padding: 10% 45%;">
    <img src="" id="screen" style="width:200px;height:200px;" />
