Links in JetPack Image Widget not working

I’ve got a lovely bar with 4 images. I’d like each image to have a link to a page on my site. I’ve gone in and specified the URL in the JetPack Image configurator, but on the page- no links.
Its the four images at the bottom of the page (Alginates, LifeCasting Kits, LifeCasting Supplies and LifeCasting Tools)
