1.I am struggling in how to replace a link with an image.

<?php
// (un): start wishlist link
echo '<a href="' . zen_href_link(UN_FILENAME_WISHLIST, 'products_id=' . YOUR_PRODUCTS_ID . '&action=un_add_wishlist') . '">' . zen_image_button(BUTTON_IMAGE_WISHLIST, BUTTON_WISHLIST_ALT) . '</a>' : ''); ?></div>
<?php
// (un): end wishlist link
?>

I keep getting an error and can't figure out the problem.

2. I want it right under my Add to Cart and not sure where to place. Again, I have moved it around and keep getting errors.

Thanking you in advance for your time and help.
