I hope i didnt confuse. what it comes down to is this


each one of those area maps links to a new page within an iframe, but i also need them to swap an image that is located on the same page (not in the iframe)

so its

Clicking Link>Swap Image>load new iframe window


somthing like that. I hope someone can help, and it would be much appreciated (will make a note on the site to your help too if it means anything to anyone)

Here you go, I coded this. Hope it is what you want. When you click the llink on the page it links the iframe to google.com and I added an onclick that executes a javascript function that changes the src of the image.

<html>
	<head>
		<script language="javascript">
function ChangeImage(){
	document.getElementById("image1").src= "http://www.daniweb.com/certificates/badge1.jpg";
}
		</script>
	</head>
	<body>
		<iframe width="800" height="600" src="http://www.daniweb.com/" frameborder="1" name="mid_nav_iframe"
			id="mid_nav_iframe"></iframe>
		<br>
		<a href="http://www.google.com/" target="mid_nav_iframe" onclick="ChangeImage();">google</a>
		<br>
		<img src="http://www.daniweb.com/certificates/badge30764.jpg" id="image1"> </TABLE>
	</body>
