    Seems like a simple thing to do and Dreamweaver MX is supposed to do it automatically.

    However, the full rollover image is not really downloading on page load when I've told it to do so. After the page is done, the first image is there, but I still have to wait 4 to 5 seconds for the over state to download when the cursor hovers over it. How do I make it so the effect is instantaneous?

    This is the code DWMX inserts:

    <script language="JavaScript" type="text/JavaScript">
    <!--
    function MM_swapImgRestore() { //v3.0
    var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
    }

    function MM_preloadImages() { //v3.0
    var d=document; if(d.Images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
    }

    function MM_findObj(n, d) { //v4.01
    var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
    if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
    for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
    if(!x && d.getElementById) x=d.getElementById(n); return x;
    }

    function MM_swapImage() { //v3.0
    var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
    if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
    }
    //-->
    </script>

    You may want to replace Dreamweaver's bloated preload script with a smaller one. There is a good one on WDF that I recall, although I can't find it at the moment. [searchwdf]Preload Script[/searchwdf]

    Also, search www.javascriptkit.com or www.hotscripts.com , they have lots of prewritten scripts that you can use.

    I've always found this one has served me well:

    You just put the images to be "postloaded" (I don't call it a preload since it occurs after the page is loaded) in an onLoad tag in the body and you call the flip portion of the script whenever you need to flip an image.
    If I've helped you out in any way, please pay it forward. My wife and I are walking for Autism Speaks. Please donate, and thanks.
