From what I've been able to see via googling, all of the code for a mouseover function starts with some code in the header...is that correct? Then the code that you have highlighted in your last post goes in the body?
quote:
function swap(num){document.getElementById('bigPic').src=pic[num] }
</SCRIPT>
In the above code, the getElementById('bigPic'), does what? Do I have to have something called bigPic?
