If your visitors are making much use of the text link, maybe it shouldn't be where it currently is, you know?
Can you add text link to the thumbnail so that both image and text appear in a single anchor element?
this is a photo of a widget base displaying the XYZ attribute.
<a href="otherpage.html" id="txtlnk">Important anchor text</a>
<a href="#" onclick="this.href=document.getElementById('txtlnk').href"><img src="compelling.gif"/></a>
