I want to set up a rollover that triggers two alternative images to change
So if there's three images: A, B & C - when B is rolled over A & C change.
I've managed to work out how to get A to change but not C as well.

This is what I mean: http://www.randam.org/test/test.html

How do I get B to trigger A & C?

This the code I'm using at the moment:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>ABC test</title>
<script type="text/javascript">
<!--
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_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_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>
</head>

<body onLoad="MM_preloadImages('A2.gif')">
<img src="A1.gif" name="A" width="30" height="30" />
<img src="B1.gif" width="30" height="30" id="A" onMouseOver="MM_swapImage('A','','A2.gif',1)" onMouseOut="MM_swapImgRestore()" />
<img src="C1.gif" width="30" height="30" />
</body>
</html>


thanks,
Rich

Just add another MM_swapImage() function to the onMouseOver of image B1.gif, using the corresponding parameters. Seperate the two functions with a semi-colon (wink.gif.

Image A1 has a name="A", while image B1 has an id="A". That doesn't seem consistent.
Anyway, you'll have to give image C1 a name or id.
