I have this functions to preload hidden images, when the mouse go over the image this preload image appear. But ... it doesn't work!:( I mean Preload doesn't do it's job!:) Every time I open the page and go over images with a mouse they start loading the hidden pictures. What's wrong with this csripts? :confused:

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) { //v3.0
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); 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];}
}

:confused:

Hi,
I think it is a logical error. preload-function loads the images which are found in document, but all pictures were allready loaded before.
Load the pictures, which are needed later on.
Good luck, skriptor

You did not post the line that calls the preload function. It would be hard to tell if you did it right.

I'm not a big fan of Dreamweaver and it's imageswap functions. Far too cluttersome.

try this..

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Untitled Document</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">

<SCRIPT LANGUAGE="JavaScript">
//Declare variables

var img1 = new Image();
img1.src = "your_source.extension";
//repeat the above as many times as you have images to preload



</SCRIPT>
</HEAD>

<BODY>
<IMG SRC="myImage.ext" NAME="myImage" onMouseover="document.myImage.src=img1.src" onMouseout="document.myImage.src=myImage.ext">

</BODY>
</HTML>
