Hi Amber,
You can add a hyperlink to your sponsor's logo in Site Designer. Select the logo image, then use the Build options panel on the right. Scroll to the bottom, enter the URL in the Image Hyperlink field, and click Save (if you're making additional changes) or Publish (if you're finished updating the webpage). I hope this will help.
Best,
Sarah Kawano
