As leaddo says it sounds like you need to add a couple of html tags to your code. If you want to display the product name rather than the url then you simply need to place the product name within the link tag.
eg.
<a href="url">Productname</a>
if you want to make images clickable you need to enclose them in the link tag.
<a href="url"><img src="imagelocation"></a>
Hope this helps
