body onload cache not clearing
<p>I'm using an image swapping function generated by Dreamweaver to allow an image to change when moused over.  The images are small.</p>

<p>I have a problem because the images are getting stored in cache and without clearing it out I cant get the new images to show.  It works on some browsers, but unfortunately not on all...</p>

<p>I've read about putting "a random query" into the javascript to force the page to reload, but I dont know where to put it (the code was generated for me by dreamweaver).</p>

<p>A subset of my code is : </p>

<pre><code>&lt;script type="text/javascript"&gt;
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&lt;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&amp;&amp;i&lt;a.length&amp;&amp;(x=a[i])&amp;&amp;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("?"))&gt;0&amp;&amp;parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&amp;&amp;d.all) x=d.all[n]; for (i=0;!x&amp;&amp;i&lt;d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&amp;&amp;d.layers&amp;&amp;i&lt;d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
  if(!x &amp;&amp; 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&lt;(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];}
}
&lt;/script&gt;
&lt;/head&gt;

&lt;body onload="MM_preloadImages('../images/navigation/social-about-us-over.jpg','../images/navigation/social-about-us.jpg','../images/navigation/social-activities-over.jpg','../images/navigation/social-ourservices-over.jpg','../images/navigation/social-howwework-over.jpg','../images/navigation/social-fundraising-over.jpg','../images/navigation/social-howtohelp-over.jpg','../images/navigation/social-contactus-over.jpg')"&gt;

<p>I'm sure there is a better way i could have written this, but if anyone can help me fix this code I'd be very grateful</p>

<p>Many thanks</p>
