Please... help with Java script thanks

Hi I'm a newbie here and very new to Java Scripting.
I found this handy little script for randomizing links but
cannot work out how to substitute a gif image as a
button instead of the "random text" lineit uses. (see below)

<SCRIPT LANGUAGE="JavaScript">
// start of script
// code by Joe Burns
// Fixed up by Zusukar
// Changed into a link-thing by Snowmit
var links = 5;
var dt = new Date();
var hr = dt.getSeconds();
var ra = hr % links;
var re = ++ra;
var msg="<A HREF=/JSBook/"+re+".html>random link";
document.write(msg);

</SCRIPT>
</A>
<P>


I have spent hours with it
any help will be greatly appreciated

 

var msg='<A HREF=/JSBook/'+re+'.html><img src='+re+'.gif/>';

 

Hi AoaoSo. Thank you for the reply. I still have a problem with the gif displaying. I checked the relative path of other images and pasted this into the code where you indicated but the gif will not display for some reason?

Cheers
Bidge

 

var msg='<A HREF=\/JSBook\/'+re+'.html ><img src=\/'+re+'.gif >';

is there an example?
