javascript rollovers

[Agata]

Hi,
here is my problem: Im working on my moms website and had this crazy idea to have rollover images for buttons.
The thing is the "mouseover" images seem to just starting to load when you hover over the link which ruins the whole effect.I used different codes, even stuff that was recomended in this forum but nothing works. ok this is what gets me: I uploaded the same page to 2 other servers and my rollovers work just fine there...
why
please help!

here are the websites:
this works:

this doesnt:

And the code:
<script language="Javascript" type="text/javascript">
<!--


if(document.images){

cen= new Image
cen1= new Image




cen.src="cennik.gif"
cen1.src="cennik1.gif"


}

else{

cen=" "
cen1=" "


document.cennik=" "

-->
</script>




<a href="cennik.html" onmouseover="document.cennik.src=cen1.src" onmouseout="document.cennik.src=cen.src">
<img src="cennik.gif" name="cennik" border="0"></a>

Aargh, Internet Explorer and its image-caching weirdnesses. As explained here, this problem is usually caused by specifying absolute urls instead of relative ones in your code. Not what you've done. Might be related to the fact that you've got a filename in the url that works, and a directory path in the one that doesn't - although adding 'index.html' doesn't help. Possibly a server configuration problem?

Hmm...just noticed some syntax errors.

else{

cen=" "
cen1=" "


document.cennik=" " ---> This is wrong, and the image reference won't even exist until the relevant HTML is parsed (farther down the page)

}

</script>
