javascript rollovers

hello javascript coders.

I am completing this site:
[url]http://www.wentworthconstructions.com.au/projects-residential-complete.html[/url]

The problem:
The image gallery in the bottom right hand corner of the page needs to “highlight” when rolled over. At the moment only the text link rolls over.

Sorry if this id really easy…i just dont have the skills.

below is the code im using so far..thanks for your help in advance.

function linkOn(refA)

{

var x = document.getElementsByTagName(“a”);

for (t=0; t<x.length; t++)

{

if (x[t] == refA)

{

x[t].style.color = “#000000”;

}

}

}

function linkOff(refA)

{

var x = document.getElementsByTagName(“a”);

for (t=0; t<x.length; t++)

{

if (x[t] == refA)

{

x[t].style.color = “#998349”;

}

}

}

document[imgName].src= imgOff;
}
