Mail.app's preferences do not allow attaching links to signatures on the Signatures preferences tab, but will accept pastes containing linked text and graphics. I wanted a graphic in my signature that when clicked would open a new mail window with my address in the To header.
Instead of creating a signature in Mail.app's preference pane, I used a new message composition window (File » New Message), dragged in a graphic file, and added a mailto:myemail@mywork.com link to the graphic with Edit » Link » Add. I then selected and copied the linked graphic, and pasted it into a new signature on the Signature tab of Mail's preferences panel. The new signature retained the graphic and its link.
I suggest using a png or jpg image, rather than a tiff (which is the default for the OS X clipboard), so your message isn't excessively large -- tiff files are sizable. If you create your graphic and save it in a compressed format, you can drag the file containing the graphic to the new message window in Mail.app; Mail will retain the image's compressed format.
[robg adds: When I tested this, it worked, but I couldn't use Edit Link in the Signature window's contextual menu. Any attempt to edit the pasted image/link would simple remove the image completely.]
