Link to product from tooltip featured image

My primary use of tooltipy is to display images over tables in woocommerce category pages with lists of individual products. I would very much like to make the tooltip image a link to the product. Is there already a way to do this (it seems an obvious enough need) or is there an easy way to create a function to do this? It seems wrapping a link around the keyword featured image is straightforward enough.

And by the way, thank you for making this freely available. It is a uniquely useful plugin. Nothing else I’ve found creates this very useful and flexible functionality.
