How do i make a custom field image a link?

Hi guys,

I have a page with a custom field named ‘whats_new_banner’. The value is the upload address of the image. How do i make this image a link? I want the link to be a custom field as well. For example;
name: whats_new_link
value: example.com/new

My current code is as follows:

<div id="home-panel">

<?php $image = get_post_meta($post->ID, 'whats_new_banner', true);
if($image) : ?>
<img src="<?php echo $image; ?>" alt="" border="0" />
<?php endif; ?>   

</div>

[Please post code snippets between backticks or use the code button.]

Any help would be much appreciated. Thanks.

Patrick.
