jQuery: Easiest way to wrap an image tag with an A anchor tag

Question

This is a simplified version of my problem.

I have two buttons, and one image. The image code is something like this

Answer 1

Try something like this:

$("img.onoff").wrap(
    $("").attr("href", "link.html"));

But perhaps using jQuery's click binding on the image itself would be better than wrapping the image in an anchor.
