I can't add a link to an icon in my email signature. It worked before and now it has stopped working.

The article Create and use email signatures in Mail on Mac - Apple Support mentions that you can "turn text into links" (I assume this means "apply a hyperlink to text") but there's no mention of applying hyperlinks to images.

I tried a few things in the signature editing panel was able to do the following:

1. Drag an email into the signature editing panel
2. Select the image
3. Use cmd+K to add a hyperlink
4. While still in the signature editing panel, click the image and observe that the link added in step 3 is loaded in my web browser.

Seems great, right? But as soon as you leave the signature editing panel (e.g. click another signature, select another Mail settings option, close the Mail settings box, etc, the image hyperlink is removed.

So the question is, "How does one force an image hyperlink to persist after it has been applied to an email signature?"

I followed the instructions on this link, tried to send myself an e-mail, but the links on the icons still did not work. Is there some step I missed after editing my signature preferences? How do I save them?
