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? ?

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];}
}

@skriptorMar 11.2003 — 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

@ksenyaauthorMar 11.2003 — OK, skriptor , I see what you meen. But how can I "load the pictures, which are needed later on"? Can you tell me??

@gil_davisMar 11.2003 — You did not post the line that calls the preload function. It would be hard to tell if you did it right.

@NicodemasMar 11.2003 — I'm not a big fan of Dreamweaver and it's imageswap functions. Far too cluttersome.

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

&lt;SCRIPT LANGUAGE="JavaScript"&gt;
//Declare variables

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



&lt;/SCRIPT&gt;
&lt;/HEAD&gt;

&lt;BODY&gt;
&lt;IMG SRC="myImage.ext" NAME="myImage" onMouseover="document.myImage.src=img1.src" onMouseout="document.myImage.src=myImage.ext"&gt;

&lt;/BODY&gt;
&lt;/HTML&gt;
